Comment 115 for bug 226470

I seem to get this when I have lots of tinderbox tabs open. Note that http://tinderbox.mozilla.org/Firefox/ has ~10 different http refreshes in it (the main page and all the tiny tinderboxen on the left side). I've had it happen at least 5-6 times now (maybe more). I thought it was mochitest doing strange things, but it wasn't. This bug caused me to file bug 403040.
