I will split this into two different bugs, seeing that the crash logs are unrelated.

This flakiness dashboard implies this test has been consistently passing for at least the last 50 builds. I checked through a random sampling of the past 200 builds and it also passed each of the 5 samples. It's also passing on ToT. Haven't bisected this to the build that stabilised the issue. Came across it while gardening, my suspicion is this can be closed.

Charlie, look into webkit-testhunter: https://github.com/clopez/webkit-testhunter The tool is slow, but it makes it easy to see more conclusively how a test has been performing without the need to look into random samples. For fast/workers/stress-js-execution.html I see the last failure seems to have been a timeout at r192773, which is a very long time ago. So I agree this test is working now. But it still has a failure expectation. We should remove the failure expectation before closing this bug. For fast/workers/worker-close-more.html I see a timeout as recently as r216135 and a crash at r215661. Still, the overwhelming majority of runs are passes, so I agree with removing the expectation and closing this bug. We have to remove the expectations first, because test expectations should always point to open bugs, not closed bugs.

So if you post a patch to remove the expectations, we can close this bug via commit-queue.

Expectations updated in bug #173160.
