Replace hardcoded delay (100 ms) with a loop awaiting until a condition is true: replace assertReturnsIfImplemented() with assertReachesEventually().

Use sleeping_retry() in assertReachesEventually() to tolerate slow buildbots and raise an exception on timeout (30 seconds).

Hi! The buildbot ARM64 Windows Non-Debug 3.x (tier-3) has failed when building commit 8a64a62.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/#/builders/730/builds/11586) and take a look at the build logs.
  4. Check if the failure is related to this commit (8a64a62) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:

It looks like the change to assertReachesEventually made test_notify_all a lot more likely to fail. I'm not exactly sure why yet.

#130933 should fix the test_notify_all failures.

I think I understand why the change to assertReachesEventually mattered. Previously, when the function was not implemented, like when getting the value of multiprocessing.Manager().Semaphore(), assertReachesEventually still called time.sleep(DELTA) ten times. Now it's faster -- no sleeping! -- but that made the existing bug in test_notify_all() more likely to occur.
