[New-bugs-announce] [issue31144] add initializer to concurrent.futures.ProcessPoolExecutor

[nvdv]

New submission from nvdv:

Unfortunately concurrent.futures.ProcessPoolExecutor does not provide any means to interact with worker processes (like initializer function in multiprocessing.Pool constructor).

This problem has been mentioned at least once: 
https://mail.python.org/pipermail/python-dev/2014-March/133697.html.

It's not hard to work around this issue by subclassing ProcessPoolExecutor and adding all necessary methods, but IMO solution can be more generic.
