NettyConnector slow to shutdown

[timfox]

I've been investigating why it seems to take at least 500 ms between closing the last session and the session close returning.

This is one of the things that has really been slowing down the test suite.

It seems that after calling NettyConnector.close() it always pauses 500ms before actually closing.

I'm thinking there's a Thread.sleep(500) or 500 ms timeout somewhere in the Netty code that's causing this problem.

Any got any ideas?

I can see the Netty selector timeout is 500.

I'm wondering if this can be interrupted at close to speed up the shutdown?

Calling ExecutorService.shutdownNow() for all ExecutorServices you specified to the constructor of ChannelFactory (i.e. NioClientSocketChannelFactory) should solve the problem. If it doesn't work, let me know.
