If you look at Condition() in threading.py, you'll see that the timeout
increases to one second over time. Note carefully that this has nothing
to do with Windows. I generally recommend that people code in a way to
avoid using timeouts. Use Queue.Queue instead.
Perhaps this should be more clearly documented.
