[issue21345] multiprocessing.Pool._handle_workers sleeps too long

[R. David Murray]

R. David Murray added the comment:

I'm not that familiar with multiprocessing, but I'd guess it was to avoid burning cpu in a busy-wait (it seems to me that that doesn't matter during finalization, but does during normal running).  Maybe it could be changed to an event wait on a shutdown event?
