Oh, but given that power failures eat disks anyway, you can just run PG 7.0
with -F and be just as fast as PG 7.1, eh? With no theoretical loss in
safety? Where's your faith in all that doom and gloom you've been
spreading? :) :)
You're right, of course, we'll get roughly -F performance while maintaining
a much more comfortable level of risk than you get with -F.
