Rather than poll our exitthread Queue in a non-blocking fashion and
always sleep for 1 second inbetween, simply call it in a blocking
fashion which will return immediately when a thread has exited. This
is somewhat faster as we don't do unnecessary sleeps after a thread
exited.
Do note that we need to specify some timeout value here (the 60 chosen
is pretty arbitary, but what the value exactly is, is not that
important, it could be any positive value) in order to make the
Queue.get() call work with SIGINT (cf
http://bugs.python.org/issue1360).
