Subject: [PATCH] This fixes a couple problems when exiting due to signal:

 * connection threads exit without closing client socket
   (so client blocks waiting for response that never comes)

 * listen_queue_thread blocks on poll() until a new connection comes in
   (because no poll timeout specified)
