I probably should have increased the default number of seconds that
pg_test_fsync runs for, in light of the fact that that can make an
appreciable difference when following this method. I'd suggest that a
value of 5 be used there. I think we should just change that, since
everyone will just use the default anyway (or, the more cautious ones
will use a higher value than the default, if anything).
