Hi,
I'm seeing intermittent Exceptions in the logs when running a test
that creates a new client, uses it, then shuts it down.
Exception in thread "Memcached IO over {MemcachedConnection to
localhost/127.0.0.1:11221 localhost/127.0.0.1:11222} - SHUTTING DOWN
(informed client)" java.nio.channels.CancelledKeyException

When I look at the source, I don't see any code that tries to prevent
the race condition between the IO handling code in
MemcachedConnection and the shutdown() call that closes each
connection. Is this a bug, or am I misreading the code?
Thanks,
David
