I know thie situation you're talking about. The simple solution is to split your authoritative and caching nameservers, so that only *external* hosts see your authoritative nameservers (with the new DNS records) whilst all your internal hosts and processes use a caching nameserver that does not know anything special about domains for which you are authoritative. Even on a single machine, you can do this by running two copies of BIND. BIND experts might be able to tell you how to do it with a single instance; I've never really looked into it.
