Bug report
Seen in https://buildbot.python.org/all/#/builders/1606/builds/220/steps/6/logs/stdio.
This looks like the same type of failures as we had with test_notify_all. It would have been nice to fix it in #130933 together with test_notify_all, but in my limited local testing of test_notify_n, I didn't see any failures.
test_notify_n (test.test_multiprocessing_spawn.test_manager.WithManagerTestCondition.test_notify_n) ... Process Process-48:
