Concurrent GC change is within that range https://trac.webkit.org/changeset/209570

I cannot repro just before or just after r209570. I will keep measuring. It's possible that my machine can't repro at all.

I also could not repro the fail in later revisions on that machine. It's probably because you need a smaller machine (like a mini) with fewer cores to get the crash. I'll try on my MBP.

Right now, the bot is stuck due to a WindowServer freeze in IOAccelEventMachine2::waitForStamp. Not sure if it's the root cause though - the current symptom is that testing doesn't start at all, while initially tests were freezing in DOM/Accessors.html.

The test is still timing out even with the concurrent GC disabled, so it looks like something else may be at fault: https://build.webkit.org/builders/Apple%20El%20Capitan%20Release%20WK2%20%28Perf%29/builds/3816

This test has ceased to time out. Latest timeout was on r209633, then it failed on r209636. This makes it a duplicate of bug 165693 I think. *** This bug has been marked as a duplicate of bug 165693 ***
