New submission from Terry J. Reedy <tjreedy at udel.edu>:

https://github.com/python/cpython/pull/28344/checks?check_run_id=3605759743
All tests pass until test_multiprocessing_fork timed out after 25 min.  On the rerun: refail with timeout.

test_get (test.test_multiprocessing_fork.WithProcessesTestQueue) ... Timeout (0:20:00)!
