Sure, but that isn't what I'm concerned about. I'm concerned about
people being lulled into a false sense of security about setting
commit_delay to 0 locally. If they do that, their actual additional
delay at commit time may well be only marginally less than the full
commit_delay, and will only rarely actually be 0.
