+ * @summary Add non-blocking SSL/TLS functionality, usable with any
+ *      I/O abstraction
+ *
+ * This is a bit hacky, meant to test various conditions.  The main
+ * thing I wanted to do with this was to do buffer reads/writes
+ * when buffers were not empty.  (buffer.position() = 10)
+ * The code could certainly be tightened up a lot.
