BIND 8 does this too, but I think Barry was thinking of not reloading
BIND at all if no zone files have been updated. If you have thousands of
zone files, making BIND stat() them all is a waste, since it affects the
performance of your name service. Having a script to it makes more
sense.

Of course, most people only have a handful to a few hundred zone files,
and simply issuing '[r]ndc reload' is fine for them.
