Between this bug and the various See Alsos, this test is quickly becoming a crash-prone trainwreck.

It really cranked up today, didn't it. I couldn't reproduce this locally on a Dec 30th build, let me try it on a fresh one, if it reproduces there may be a patch that increased the frequency.

I think backed out the cause for the immediate spike. It waits to be seen if that's right, though. https://bugzilla.mozilla.org/show_bug.cgi?id=567058#c27

Ryan - did the backout help?

Yes
