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.
