You can load the forwarded zones from an external file (forward-zones-file). 
You can reload that list with rec_control reload-zones, without restarting
the nameserver.  I really suggest you do that.

All other solutions are painful.

And what if a packet is dropped? Ask the rootservers anyhow? The best way
really is to provision that list of zones.
