+ * Manager of incoming debugger events for a target VM.

+ * EventSets generated by the debugger back end can be read
+ * here. There is one instance of EventQueue assigned to a particular
+ * {@link com.sun.jdi.VirtualMachine VirtualMachine}.
+ * <P>
+ * Some events cause the suspension of the target VM - event requests
+ * ({@link com.sun.jdi.request}) with a
+ * {@link com.sun.jdi.request.EventRequest#suspendPolicy() suspend policy}
+ * of {@link com.sun.jdi.request.EventRequest#SUSPEND_ALL SUSPEND_ALL}
+ * or {@link com.sun.jdi.request.EventRequest#SUSPEND_EVENT_THREAD
+ * SUSPEND_EVENT_THREAD} and sometimes
+ * {@link VMStartEvent}.
+ * If these suspensions are not resumed the target VM will hang.
+ * Thus, it is always good policy to
+ * {@link #remove() remove()} every EventSet from the
+ * event queue until an EventSet containing a
+ * {@link VMDisconnectEvent} is read.
+ * Unless {@link com.sun.jdi.VirtualMachine#resume() resume} is
+ * being handled in another way, each EventSet should invoke
+ * {@link EventSet#resume()}.
