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.
