FWIW, I kicked off a looong benchmarking run on this a couple of days
ago on the IBM POWER7 box, testing pgbench -S, regular pgbench, and
pgbench --unlogged-tables at various client counts with and without
the patch; three half-hour test runs for each test configuration.  It
should be done tonight and I will post the results once they're in.
