Yeah, we realized last year that no supported platform has worse than
1usec gettimeofday resolution anymore [1].  So I think you're right
that we could shave some milliseconds off stats.sql, as well as some
other test scripts.  I doubt this'd make for a meaningful time
savings, but perhaps it's worth doing just for consistency: grepping
for pg_sleep in our tests, I see anywhere from 0.1 to 0.001 sec.
