This is for sure valid for a running bind, but after a restart all
caches are emptied, right? We're currently in a big reconfiguration, so
bind restarts happen more often than I would want. Having
the .in-addr.arpa zone locally saves at least the 1st level lookups,
thus helping after a restart, or isn't that worth the simple zone copy?
