I'm still unable to reproduce :-( --- I ran about two dozen cycles
overnight with no sign of trouble.  This time I was using a master/slave
pair with the test database in a non-default partition, so neither of
those aspects seem to be key after all.

I suspect the reason for it being so hard to reproduce is that there's
a timing window involved.  But that doesn't offer much to go on in
terms of being able to make a more reproducible case.
