Sometimes running mochitests, I hit: WARNING: An event was posted to a thread that will never run it (rejected): file /home/andrew/tbox/SeaMonkey-mochi/Linux_220.127.116.11-72.fc6_Depend/mozilla/xpcom/threads/nsThread.cpp, line 359 WARNING: leaking reference to nsTimerImpl: file /home/andrew/tbox/SeaMonkey-mochi/Linux_18.104.22.168-72.fc6_Depend/mozilla/xpcom/threads/nsTimerImpl.cpp, line 464 ... and then the tests stop running. I have to quit SeaMonkey or wait for runtests to timeout. I suspect this happens occasionally on the FF tboxes but they don't build debug, so it just shows up as a mystery hang. This probably also happens outside of mochitest, but the app remains usable, so nobody notices.

If you can get a decent test case, that consistently reproduces the hang, then great. 'Til then -'ing.
the warning is from bug 404870
