It looks like a deadlock. I can't say if it will hang *forever* on
the scale of geological time but it was stuck long enough for me to
attach a debugger and also to wait while I stepped away for an hour
to take a call. It looked like the thread was waiting for something
to be released which had been locked higher up the stack. I'd say
it's a deadlock.
A few months ago there was a post by Daniel K here or on the commits
list about exactly this scenario. These sort of hangups were a lot
more common back then so I suppose this is some corner case that has
escaped detection. It would be good to track it down before the
imminent release.
Anyway I was mostly looking for a pointer on how that part of the
code works so I can hit the ground running the next time it sticks.
It never seems to happen when I have a few spare hours on my hands.
