+     * This is an implementation of a concurrent lock-free deque
+     * supporting interior removes but not interior insertions, as
+     * required to support the entire Deque interface.
+     *
+     * We extend the techniques developed for ConcurrentLinkedQueue and
+     * LinkedTransferQueue (see the internal docs for those classes).
+     * Understanding the ConcurrentLinkedQueue implementation is a
+     * prerequisite for understanding the implementation of this class.
+     *
+     * The data structure is a symmetrical doubly-linked "GC-robust"
+     * linked list of nodes.  We minimize the number of volatile writes
+     * using two techniques: advancing multiple hops with a single CAS
+     * and mixing volatile and non-volatile writes of the same memory
+     * locations.
+     *
+     * A node contains the expected E ("item") and links to predecessor
+     * ("prev") and successor ("next") nodes:
+     *
+     * class Node<E> { volatile Node<E> prev, next; volatile E item; }
+     *
+     * A node p is considered "live" if it contains a non-null item
+     * (p.item != null).  When an item is CASed to null, the item is
+     * atomically logically deleted from the collection.
+     *
+     * At any time, there is precisely one "first" node with a null
+     * prev reference that terminates any chain of prev references
+     * starting at a live node.  Similarly there is precisely one
+     * "last" node terminating any chain of next references starting at
+     * a live node.  The "first" and "last" nodes may or may not be live.
+     * The "first" and "last" nodes are always mutually reachable.
+     *
+     * A new element is added atomically by CASing the null prev or
+     * next reference in the first or last node to a fresh node
+     * containing the element.  The element's node atomically becomes
+     * "live" at that point.
+     *
+     * A node is considered "active" if it is a live node, or the
+     * first or last node.  Active nodes cannot be unlinked.
+     *
+     * A "self-link" is a next or prev reference that is the same node:
+     *   p.prev == p  or  p.next == p
+     * Self-links are used in the node unlinking process.  Active nodes
+     * never have self-links.
+     *
+     * A node p is active if and only if:
+     *
+     * p.item != null ||
+     * (p.prev == null && p.next != p) ||
+     * (p.next == null && p.prev != p)
+     *
+     * The deque object has two node references, "head" and "tail".
+     * The head and tail are only approximations to the first and last
+     * nodes of the deque.  The first node can always be found by
+     * following prev pointers from head; likewise for tail.  However,
+     * it is permissible for head and tail to be referring to deleted
+     * nodes that have been unlinked and so may not be reachable from
+     * any live node.
+     *
+     * There are 3 stages of node deletion;
+     * "logical deletion", "unlinking", and "gc-unlinking".
+     *
+     * 1. "logical deletion" by CASing item to null atomically removes
+     * the element from the collection, and makes the containing node
+     * eligible for unlinking.
+     *
+     * 2. "unlinking" makes a deleted node unreachable from active
+     * nodes, and thus eventually reclaimable by GC.  Unlinked nodes
+     * may remain reachable indefinitely from an iterator.
+     *
+     * Physical node unlinking is merely an optimization (albeit a
+     * critical one), and so can be performed at our convenience.  At
+     * any time, the set of live nodes maintained by prev and next
+     * links are identical, that is, the live nodes found via next
+     * links from the first node is equal to the elements found via
+     * prev links from the last node.  However, this is not true for
+     * nodes that have already been logically deleted - such nodes may
+     * be reachable in one direction only.
+     *
+     * 3. "gc-unlinking" takes unlinking further by making active
+     * nodes unreachable from deleted nodes, making it easier for the
+     * GC to reclaim future deleted nodes.  This step makes the data
+     * structure "gc-robust", as first described in detail by Boehm
+     * (http://portal.acm.org/citation.cfm?doid=503272.503282).
+     *
+     * GC-unlinked nodes may remain reachable indefinitely from an
+     * iterator, but unlike unlinked nodes, are never reachable from
+     * head or tail.
+     *
+     * Making the data structure GC-robust will eliminate the risk of
+     * unbounded memory retention with conservative GCs and is likely
+     * to improve performance with generational GCs.
+     *
+     * When a node is dequeued at either end, e.g. via poll(), we would
+     * like to break any references from the node to active nodes.  We
+     * develop further the use of self-links that was very effective in
+     * other concurrent collection classes.  The idea is to replace
+     * prev and next pointers with special values that are interpreted
+     * to mean off-the-list-at-one-end.  These are approximations, but
+     * good enough to preserve the properties we want in our
+     * traversals, e.g. we guarantee that a traversal will never visit
+     * the same element twice, but we don't guarantee whether a
+     * traversal that runs out of elements will be able to see more
+     * elements later after enqueues at that end.  Doing gc-unlinking
+     * safely is particularly tricky, since any node can be in use
+     * indefinitely (for example by an iterator).  We must ensure that
+     * the nodes pointed at by head/tail never get gc-unlinked, since
+     * head/tail are needed to get "back on track" by other nodes that
+     * are gc-unlinked.  gc-unlinking accounts for much of the
+     * implementation complexity.
+     *
+     * Since neither unlinking nor gc-unlinking are necessary for
+     * correctness, there are many implementation choices regarding
+     * frequency (eagerness) of these operations.  Since volatile
+     * reads are likely to be much cheaper than CASes, saving CASes by
+     * unlinking multiple adjacent nodes at a time may be a win.
+     * gc-unlinking can be performed rarely and still be effective,
+     * since it is most important that long chains of deleted nodes
+     * are occasionally broken.
+     *
+     * The actual representation we use is that p.next == p means to
+     * goto the first node (which in turn is reached by following prev
+     * pointers from head), and p.next == null && p.prev == p means
+     * that the iteration is at an end and that p is a (final static)
+     * dummy node, NEXT_TERMINATOR, and not the last active node.
+     * Finishing the iteration when encountering such a TERMINATOR is
+     * good enough for read-only traversals, so such traversals can use
+     * p.next == null as the termination condition.  When we need to
+     * find the last (active) node, for enqueueing a new node, we need
+     * to check whether we have reached a TERMINATOR node; if so,
+     * restart traversal from tail.
+     *
+     * The implementation is completely directionally symmetrical,
+     * except that most public methods that iterate through the list
+     * follow next pointers ("forward" direction).
+     *
+     * We believe (without full proof) that all single-element deque
+     * operations (e.g., addFirst, peekLast, pollLast) are linearizable
+     * (see Herlihy and Shavit's book).  However, some combinations of
+     * operations are known not to be linearizable.  In particular,
+     * when an addFirst(A) is racing with pollFirst() removing B, it is
+     * possible for an observer iterating over the elements to observe
+     * A B C and subsequently observe A C, even though no interior
+     * removes are ever performed.  Nevertheless, iterators behave
+     * reasonably, providing the "weakly consistent" guarantees.
+     *
+     * Empirically, microbenchmarks suggest that this class adds about
+     * 40% overhead relative to ConcurrentLinkedQueue, which feels as
+     * good as we can hope for.

+ZipFileSystem is a file system provider that treats the contents of a zip or
+JAR file as a java.nio.file.FileSystem.
+
+To deploy the provider you must copy zipfs.jar into your extensions
+directory or else add <JDK_HOME>/demo/nio/ZipFileSystem/zipfs.jar
+to your class path.
+
+The factory methods defined by the java.nio.file.FileSystems class can be
+used to create a FileSystem, eg:
+
+   // use file type detection
+   Map<String,?> env = Collections.emptyMap();
+   Path jarfile = Path.get("foo.jar");
+   FileSystem fs = FileSystems.newFileSystem(jarfile, env);
+
+-or
+
+   // locate file system by URI
+   Map<String,?> env = Collections.emptyMap();
+   URI uri = URI.create("zip:///mydir/foo.jar");
+   FileSystem fs = FileSystems.newFileSystem(uri, env);
+
+Once a FileSystem is created then classes in the java.nio.file package
+can be used to access files in the zip/JAR file, eg:
+
+   Path mf = fs.getPath("/META-INF/MANIFEST.MF");
+   InputStream in = mf.newInputStream();
