That would be great.  Taking a look at what happened, I have a feeling
this may be a race condition of some kind in the isolation tester.  It
seems to have failed to recognize that a1 started waiting, and that
caused the "deadlock detected" message to reported differently.  I'm
not immediately sure what to do about that.
