Hmm.  This seems to mean that we're somehow missing a relation mapping
invalidation message, or perhaps not processing it soon enough during
some complex set of invalidations.  I did some testing with that in mind
but couldn't reproduce the failure.  It'd be awfully nice to get a look
at the call stack when this happens for you ... what OS are you running?
