Description

Apparently a TI regression: I saw a couple of these on Jaegermonkey, and this instance is from the merge to mozilla-central.

http://tbpl.allizom.org/php/getParsedLog.php?id=6183059 and http://tbpl.allizom.org/php/getParsedLog.php?id=6183260 for a couple of recent JM ones, suspiciously on the same build, though the third time I retriggered on that build it passed.
Oh, this. This is an actual bug in our code. Somehow it hadn't been causing trouble until now. Test patch coming as I don't have time to fix the actual bug now and it doesn't matter hugely.
...and it does make sense that it would be triggered by a JS engine change. See the discussion in bug 630672

disable the uniqueObjectTest

This test is valid, but flaky as it relies on GC happening at a particular time. A recent JS engine change making it actually happen caused it to actually catch a bug we've always had in the OES_texture_float impl, see the discussion on bug 630672, and I don't have time to fix that now.

Personally, I'd prefer if you included the explanation of the problem inline.

don't ignore this test on linux

This intermittent orange is really fixed by this patch. But we're still ignoring this test on linux as I first noticed it there and did improper analysis. This patch un-ignores this test.
