cc @jsulz , if you want we can run the tests in a loop to see if they fail at any point (for the bugged version they would fail about half the time)

ran the test 2 times (I can rerun again, both successes)

@clefourrier when I was testing this prior to the fix, I was able to get into a failed state ~20% of the time (for reasons beyond my understanding, this CI test was particularly adept at triggering the error).

If it's possible to run this in a loop for some finite number of times (in the range of 10ish iterations - I know that's quite a few 😬) that would likely be sufficient. 🙏

We'll just keep the branch as is and update it with main regularly to force the test to go through

[jsulz]

Well, we're 6 runs in and it looks like all tests have succeeded (we've also had reports from other folks that this particular issue has abated).

I think you can merge this whenever you feel comfortable.

Thanks again for raising this (and providing a nice test bed for the issue). Appreciate it!
