Thanks for the pointer.  That looks very promising.

Hoping to be able to test your fix, I rsync'd the offending repository to
a system on which I can experiment safely, but so far have been unable
to reproduce the failure there.  Of course, if my problem is indeed due
to the race condition bug that your patch fixes, it's not surprising
that it is unreproducible in a different environment.
