| Unfortunately, the race condition can't be removed completely - it was reduced by the patch in #14632 but could not be eliminated altogether. So this test can fail sporadically - tweaking the timeouts might give some temporary respite, but doesn't guarantee the issue won't return when e.g. machines are unusually heavily loaded. I'll add some diagnostics for now and see what they show. |

| I'll close this for now as the failures seem to have stopped. Though I only added some diagnostics, that might have changed the relative timings enough so the race doesn't surface (for now). |

| What is the status of this issue?

| > What is the status of this issue? Sorry, it's been off my radar - I wonder if it has become more common recently. It's hard to reproduce, and tweaking timeouts might make it disappear, but it's a trial-and-error situation because I can hardly ever get the error to occur. The base race condition can't be eliminated, unfortunately. |
