Hmmm ....
http://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=spoonbill&dt=2016-02-27%2000%3A00%3A06
This failure looks a lot like the timing-related problems I was chasing
last week with deadlock-hard on the CLOBBER_CACHE_ALWAYS critters.
spoonbill isn't CLOBBER_CACHE_ALWAYS, but it uses some weird malloc debug
stuff that slows it down by similar orders of magnitude. You seem to need
to think about how to make this test less timing-dependent.
