Created attachment 456951 [details] [diff] [review] Back out bug 573669 The event loop pausing code (bug 573669) crashes and also breaks background downloads. We should back it out for now.
Comment on attachment 456951 [details] [diff] [review] Back out bug 573669 I'd really like to understand this crash better rather than just back out.
I'm not seeing this, can you post steps to reproduce?
Can't reproduce anymore. Something else must've fixed it.
