This whole subthread seems like a distraction to me. I find it hard
to believe that this test case would be stable enough to survive the
buildfarm where, don't forget, we have things like
CLOBBER_CACHE_ALWAYS machines where queries take 100x longer to run.
But even if it is, surely we can pick a less contrived test case. So
why worry about this?
