Barrie Treloar updated DIRMINA-632:

(I've had to manually hack the mina-2.0-handle-write-exceptions-test.txt file to remove the
non-relevant changes)

> This is best shown with UDP since TCP will cause a close session to occur.
> If channel.write() throws an exception, e.g. the host becomes unreachable because of
network connection is removed, then WriteFuture.awaitUninterruptibly() will hang - as it will
never have setWritten(false) or setException() called.
> I have modified the MemoryMonitor example to show this happening.
> You must manually pull your network cable (or disable your Network Adapter) while the
client is running to see this happen.
