> If your machine has the resources for doing so, I'd recommend running multiple instances of BIND, which will enable you to stop/start your test-instances at will.  Furthermore you'll probably find configuration of individual BIND name servers easier to create and manage. On the down-side you'll need monitoring for the N instances, you'll probably have N logs, etc.

Rather than running multiple bind instances on one server, is virtualization an option for you? Thus you could build multiple virtual machines each running a single bind instance.
