Uh ... what? How would that not be broken usage on its face?
I continue to think that we'd be better off getting all of this
out of the heavyweight lock manager. There is no reason why we
should need deadlock detection, or multiple holds of the same
lock, or pretty much anything that LWLocks don't give you.
