[Bug 1628763] [NEW] Example of Queue from documentation fails

[Kevin O'Gorman]

Public bug reported:

Reading https://docs.python.org/3.5/library/multiprocessing.html
#exchanging-objects-between-processes, I have copy-pasted the code into
a file.  Running it with python3 fails thus:

Traceback (most recent call last):
  File "q.py", line 7, in <module>
    q = Queue()
  File "/usr/lib/python3.5/multiprocessing/context.py", line 100, in Queue
    from .queues import Queue
  File "/usr/lib/python3.5/multiprocessing/queues.py", line 20, in <module>
    from queue import Empty, Full
ImportError: cannot import name 'Empty'


I will attach the actual code file.
