In #551 @martijnwalraven tried turning on the Thread Sanitizer, and that's led to some maddeningly inconsistent failures on CI. I was suddenly able to reproduce a bunch of times this morning, but when working with him today, I was not able to reproduce using exactly the same laptop/simulator/code. Martijn can't repro on his end either.
After trying and trying to repro this afternoon, our strong hunch is this is a long-standing problem that's been uncovered by turning on TSAN and not anything to do with his PR. I'm opening this issue to put a pin in it so we can try to figure out what's happening once we've dealt with some more urgent issues.
