Attachment: trigger GC frequently on linux i686

Jeff had the idea that this could be caused by the slaves running out of (video) memory, which fits well with the fact that the JS engine tends to keep unreferenced WebGL contexts around very long before GCing (see bug 617453). This patch triggers a GC before starting every webgl test page.

on try:
https://tbpl.mozilla.org/?tree=Try&rev=a3d9424c6296

retrigger a dozen times to check if it fixes the problem.

All green after 12 retriggers. Will land tomorrow.

Very interesting to see that it also happens on 64bit slaves. Will update patch accordingly.

that's not needed and easy to miss, indeed it already happened. Landing on m-c should immediately mark bugs as fixed, they can always be reopened indeed.

This is a special case: this bug and bug 696009 have been used to star very frequent intermittent oranges. Having them marked as fixed before oranges were completely gone on inbound could have confused people trying to star oranges there. I was not going to forget about it. Thanks for closing though.
