That is very cool, and generally useful enough that maybe it should be
dropped into itertools.  I see that Queue.get's implementation is
quite intricate (it uses three separate locks to handle some
additional cases like timeouts and non-blocking gets) but I'm not up
to trying to grok it right now.  Thanks!
