Look how concurrent.futures uses it:
https://github.com/python/cpython/blob/master/Lib/concurrent/futures/process.py#L348

This also means:
1) we could redirect people to ProcessPoolExecutor instead of trying to backport all its features into multiprocessing.Pool
2) we could try to refactor the ProcessPoolExecutor implementation into a common backend for both ProcessPoolExecutor and multiprocessing.Pool
