Any idea why this has started failing every now and then after a year of everything being okay?
Boris, as test reviewer, any ideas? It's failing at: http://hg.mozilla.org/mozilla-central/file/3825fdbcec62/xpcom/tests/unit/test_bug325418.js#l39

Might have been nicer as Math.abs(Date.now() - gStartTime1) < 0.5 (or some smaller value), but not required.

> r=me if the infallible part is unrelated and removed. It's totally unrelated, and shall be removed. It was just in that tree when I started editing, apparently. Good catch! > which would be OK for this test with these values of 5, 1. Right. If the timeout values weren't those we'd have to do something smarter, but they are, so...
Avi, did you mean to mark r+ on the patch?
Assuming so, and trying to avoid extra randomorange: https://hg.mozilla.org/integration/mozilla-inbound/rev/2a09d354053f

(In reply to Boris Zbarsky (:bz) from comment #40) > Avi, did you mean to mark r+ on the patch? Sure. By the time I finished playing with splinter I forgot to change to r+. Guess it's acceptable for a first review, even if a bit messy (/1000!) ;)
