    <thetext>I cannot repro just before or just after r209570.

I will keep measuring.  It&apos;s possible that my machine can&apos;t repro at all.</thetext>

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

I also could not repro the fail in later revisions on that machine.

It&apos;s probably because you need a smaller machine (like a mini) with fewer cores to get the crash.  I&apos;ll try on my MBP.</thetext>

    <thetext>Right now, the bot is stuck due to a WindowServer freeze in IOAccelEventMachine2::waitForStamp.

Not sure if it&apos;s the root cause though - the current symptom is that testing doesn&apos;t start at all, while initially tests were freezing in DOM/Accessors.html.</thetext>

    <thetext>The test is still timing out even with the concurrent GC disabled, so it looks like something else may be at fault:

&gt; Apple%20El%20Capitan%20Release%20WK2%20%28Perf%29/builds/3816

Could still be my patch, since it was a big one - but it&apos;s looking less likely.</thetext>

    <thetext>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.
