It keeps wanting to destroy itself when attached to the session filter chain. (I thought before there was a filter chain that was below the session, and then the session filter chain, but it appears that there is only one now, and it is tied to the session?
I am only attaching it on the Acceptor side, using: (there's no example of using it with an Acceptor)
SocketAcceptorConfig config = new SocketAcceptorConfig();
config.setReuseAddress( true );
config.getFilterChain().addFirst( "ThreadPool",
threadPoolFilter );
followed by
acceptor.bind( socketAddress, this, config );
.. in a thread dump, I keep seeing:

.. that is, I have 4 threads that all think that they should be destroying the ThreadPoolFilter, and effectively locking my stuff up.
now, seems to me that constantly destroying the ThreadPoolFilter goes against what it should be doing.. even if the system is idle, I would want to have some pooled threads hanging about waiting for some load to occur..
.. to dig deeper, I'm not sure I like the idea of having IoFilter lifecycle automatically managed by reference counting of how many times it is in use.. what if I know better, and I want to have some global filters I create one at startup, and then destroy at shutdown?
