Thanks. Hmm, something is wrong here because make check is
dramatically slower -- for example the "insert" test runs in ~8-13
seconds instead of the usual ~0.2 seconds according to Travis,
AppVeyor and my local FreeBSD system (note that fsync is disabled so
it's not that -- it must be bogus queue-related CPU?)
