[New-bugs-announce] [issue26762] test_multiprocessing_spawn leaves processes running in background

[Martin Panter]

New submission from Martin Panter:

I noticed that this test leaves processes running in the background for a moment after the parent Python process exits. They disappear pretty quickly, but even so, it seems like a bad design. However I am not familiar with the multiprocessing module, so maybe this is unavoidable.

$ ps
  PID TTY          TIME CMD
  597 pts/2    00:00:01 bash
13423 pts/2    00:00:00 ps
$ python3.5 -m test test_multiprocessing_spawn; ps
[1/1] test_multiprocessing_spawn
1 test OK.
