[issue11815] Simplifications in concurrent.futures

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

A further optimization would be to use a SimpleQueue (from multiprocessing.queues) for the result_queue in the ProcessPoolExecutor. A SimpleQueue is much more light-weight than a normal Queue, which has a bunch of additional locks and a dedicated thread.
