In Python 3.3, multiprocessing.Process.join() is not blocking with floats lower than 1.0 (not included). It works as expected (ie. blocking for the specified timeout) in Python 2.6->3.2

As you can see in this example, calling join() with 0.99 returns immediately.

>>> import time
>>> import multiprocessing
>>> def foo():
...  time.sleep(1000)

>>> p = multiprocessing.Process(target=foo)
>>> p.start()
>>> bar = time.time(); p.join(0.99); print(time.time()-bar)
0.015963315963745117
>>> p.is_alive()
True
>>> bar = time.time(); p.join(1.0); print(time.time()-bar)
