.. class:: Queue([maxsize])

.. note::
Unlike :class:`queue.Queue`, :class:`multiprocessing.Queue` does not
implement the :meth:`~queue.Queue.shutdown` method.

Returns a process shared queue implemented using a pipe and a few
locks/semaphores. When a process first puts an item on the queue a feeder
thread is started which transfers objects from a buffer into the pipe.
