Fix potential flakiness in test_run_until_complete_baseexception

[fantix]

Refs #24477, use a more reliable way to run the test.

If the covering issue happens again, the loop would be requested to stop in the first iteration and got stopped after the first iteration. In that case, our func() in the second iteration won't be called.

Done & merged.

This is indeed better than sleeping for a small delay.

[gvanrossum]

Yup, a very insightful solution. Thanks @fantix !

This PR appears to have resulted in an empty commit, likely because the PR branch was not fully up to date with main: a9bad4d :/

Very weird. Especially since when I check out main and pull to head, the change is there, and attributed to this PR. So maybe the problem is with the GitHub UI? I saw some mention of enpty branches on Discord but chose to ignore it.

[AlexWaygood]

Oh, weird. Yes, I see the same. It must be something wrong with the GitHub UI. My sincere apologies for the false accusation, @fantix!

[fantix]

No worries @AlexWaygood , thank you for being careful ❤️

[gvanrossum]

Hm, there's definitely something weird though. I see three commits for this PR in the main branch:

Two of those are empty. What kind of GitHub hiccup could have caused that???

[kumaraditya303]

Possibly we can report this to GitHub somehow or ask anyone from GitHub to look at this? I don't know how to do it though.
