Steve Dower <[email protected]> added the comment:
I suspect this code is a repro - it certainly locks up the host process
reliably enough.
Perhaps if we unblock multiprocessing in the context of a crashed worker then
it'll show what the underlying errors are?
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]))
