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.
