[issue24484] multiprocessing cleanup occasionally throws exception

[Jorge Herskovic]

Jorge Herskovic added the comment:

20,000+ iterations of the test suite with my homebuilt 3.4.3 throw no exceptions. 

Weirder and weirder. 

Any suggestions? Without any actual knowledge ("unencumbered by the thought process"), a concurrency issue in the interpreter itself is my guess. Especially since I can't reproduce it at all on other versions. 

I'll see if I can come up with a shorter, self-contained test that can illustrate the issue too.
