Could it be a hardware problem on Marc's box? Or specific to some other
aspect of that installation (Marc, is pgsql74.hub.org multi-CPU, for
example?)

The failure is definitely quite repeatable on pgsql74.hub.org. I don't
see it on svr1.postgresql.org, though, which seems to be running almost
the same kernel.
