My comments are perhaps not useful, but I know OS X does some 
interesting things with persistent TCP connections.  My settings mirror 
yours on my NetBSD systems at home.  On my Powerbook I can put it to 
sleep, awaken it 20 minutes later and as long as my net interface 
hasn't changed, I still have an active ssh connection.
