I don't think it's a bug, it seems to meaningful since all the blocking
calls have this behaviour. Looks like SM has stack pausing / continuing in
place as well; why, if not for this? Seems reasonable to me. But if it's a
bug, I'm extremely sorry I haven't filed it, I didn't think it was a bug
when I discovered it around Fx8.

Yes, this is Firefox-specific. I've tested all other browsers at my
disposal and they don't have this behavior. Seems like a good idea adding
it though, could make the browsers a lot more responsive regardless of a
few bad websites, and I don't think those websites would break horribly
because of this.
