I'm not crazy about putting this in Core::General, but it wasn't immediately clear to me where to put it otherwise. The leaking directory is dom/tests/mochitest/ajax/prototype, which apparently only ran one test.

Hello, I'm asking your help with an experiment with making decisions on bugs. You've been needinfo'ed on this bug. I'd like you to take one action to help this bug make progress toward a decision. The things you can do include:

* If you know or have a good guess of which product and component this bug belongs to, change the product and component of the bug
* If you know of the right person to ask about this bug, redirect the needinfo to them
* If you cannot reproduce the bug, close it

All we need you to do is one thing that will help us make a decision on the bug or resolve it.

Thank you for your help with this. If you have questions, please contact [e-mail].

I have no clues; I usually don't work on the browser but on Spidermonkey and the standalone JS shell executable, so I never see this kind of leak.

Standing out from the logs, the GC seems to complain that at shut down, many things have not been freed ("SharedScriptData"), and some atoms refcount is non zero. Randomly picking mccr8 who I *think* is working on memory management in general, sorry I won't be able to do much more here. Good luck!

Comment 8

[Andrew McCreight [:mccr8]]

This is a rare intermittent leak. I don't think it is worth spending much time on. It has happened once in the last week, in the XBL test directory, so it shouldn't be closed. We're leaking chrome JS stuff so maybe something isn't shutting down correctly.
