[New-bugs-announce] [issue33997] multiprocessing Pool hangs in terminate()

[Erik Wolf]

New submission from Erik Wolf <erik.wolf.87 at gmail.com>:

The terminate() method of multiprocessing.Pool hangs sporadically.
I could track this issue down to the fact that _handle_results() hangs in the outqueue-cleanup. poll() returned True but get() actually hangs endlessly never returning any data.
