New submission from Steve Dower <[email protected]>:
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.
