[New-bugs-announce] [issue38084] multiprocessing cannot recover from crashed worker

[Steve Dower]

New submission from Steve Dower <steve.dower at python.org>:

Imitation repro:

import os
from multiprocessing import Pool

def f(x):
    os._exit(0)
    return "success"

if __name__ == '__main__':
    with Pool(1) as p:
        print(p.map(f, [1]))


Obviously a process may crash for various other reasons besides os._exit().

I believe this is the cause of issue37245.
