It's not that Queue.Queue is "better" than RLock (Queue was written
before threading.py, but if it had been written after, I would
expect it to use a Condition which uses an RLock.)
What's "better" is keeping the number of "shared" (really, "contended")
resources to a minimum. If your threads only meet through Queues,
you have virtually no chance of ending up deadlocked.
It's really a design philosophy: each resource should be owned
by one and only one thread.
