Thanks very much for this, I'm running it at the moment.  So far, with
the transaction isolation patch (the one which does not run the error in
its own transaction) and the "new" Transience.py, and an
unmodified-from-stock TemporaryStorage I haven't yet been able to
provoke any unseemly errors out of transience... <wait>... as I typed
that, I just saw one go by! ;-)  Excellent.  I will diagnose.
