adding zone forwards without restart

The basics are fine.  BIND just doesn't load newly added forwarded zones,
period.  It also kind of lies in the output:

Sep 20 17:57:48 host01 named[26453]: reloading configuration succeeded
Sep 20 17:57:48 host01 named[26453]: any newly configured zones are now
loaded

...except they're not.  Thus far I think the only condition I've actually
seen BIND load new zones without a restart after being added to named.conf
is if it's not already authoritative for a lower level part of a domain and
you're adding an authoritative zone.

Even adding another master zone that is higher up in the hierarchy will not
load until a full restart I've found (meaning you have "domain.com"
configured as a master zone and add "subdomain.domain.com" as a master zone
as well).
