Too many open files error with Netty

I just tested with revision 1842 from Netty SVN, but there still seems
to be a problem.

After about 78000 connections on our Solaris box, I got the following:

Oct 27, 2009 10:39:12 AM org.jboss.netty.channel.socket.nio.NioWorker
WARNING: Unexpected exception in the selector loop.

Watching the heap in Visual VM also seems to indicate that it keeps growing.

Regards,

Albert

P.S. Code attached again.
