I have good news and bad news.

The good news: Even though your core show locks showed no apparent
deadlock, I was able to figure out where the deadlock was occurring thanks
to the backtrace you uploaded. I also fixed a bug in the code which helps
to generate the list of locks for the "core show locks" command so
hopefully future output will be more helpful.

The bad news: The culprit for this deadlock is app_chanspy and the
appropriate fix is not obvious. I'm going to assign this to Russell so he
can figure out what to do about it.
