bobby: this seems a new intermittent leak in stylo tests, could you take a look, thanks!
Flags: needinfo?(bobbyholley)
Looks like this started with the landing of bug 1315601. Seems to be happening about 80% of the time so we should jump on this quickly.

Over to xidorn.

The earliest push with this leak is from bug 1341690:

The URL change seems to be a more sensible candidate since bug 1315601 doesn't have much work on string stuff.

I assume heycam would know more.

FWIW, according to my local run last night, it seems to me the leak happens inside one of layout/reftests/{dom,generated-content}. I saw them intermittently, but failed to further locate where the issue is.
Also, this bug can be from bug 1296477, which makes more sense with the generated-content bits. manish?
Flags: needinfo?(manishearth)
Yeah, that is possible as well, since the task crashes before bug 1341690's push.
No longer blocks: 1315601
It is layout/reftests/dom/xbl-children-3.xhtml leaking.

I'm going to disable this test in this bug, and file a new bug investigating the reason.
