      * Used to synchronize concurrent access to an ASynchChannel.

32 |  |
      * Uses a {@see EDU.oswego.cs.dl.util.concurrent.Sync} object
33 |  |
      * for write operations.  All other operations such as {@see #stop(long)}
34 |  |
      * and {@see #stop} just do a normal java synchronization against the SynchornizedSynchChannel
35 |  |
      * object instance.  It is assumed that the Async message delivery is not
36 |  |
      * concurrent and therefore does not require synchronization.
