Subject: This fixes a couple problems when exiting due to signal:
X-Git-Url: https://git.octo.it/?p=rrdtool.git;a=commitdiff_plain;h=81c5c973ffc8e6d305f533f5ea2e6e407beca865

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)
