Probably a regression in https://go.dev/cl/506415? (attn @mknyszek, @rsc)

I see, the test didn't actually used to check how much contention accumulated, now it requires contention to be within [9 seconds, 20 seconds].

It may actually be that this is too flaky a condition to try and write a test about. A lot of these are only just over the threshold, but the s390x failure is waaaaay over.

Here's an idea: only check the lower-bound, not the upper bound. That's really all the new behavior is about anyway. OS scheduling can always interfere and make the timing go sky-high. It's much harder to make the time be less than that, though there is still an opportunity because the sleep happens before all the other goroutines have properly blocked.

OK, I have an idea. I will send a patch. At the very least it should downgrade this issue from Soon, even if it doesn't fully resolve the flakes.

Can the contention be bounded above by something else (maybe time.Since(start)*time.Duration(runtime.NumCPU())? (Or is it counting contention per-goroutine instead of per thread?)

It's contention per goroutine. I didn't totally remove the upper bound, but it set it to be on the order of a test timeout.

I think the only non-flaky way to really check the math would be to stub out time altogether, but that's pretty difficult to do.

This last one from linux-mipsle-rtrk is real. All the other ones are from before the fix.

@mknyszek mknyszek removed release-blocker Soon This needs to be done soon. (regressions, serious bugs, outages) labels Sep 13, 2023

Removed release-blocker and Soon labels because this has only appeared on linux-mipsle-rtrk after the test fix. The rate of failures is also clearly very low at this point.
