	Yes, but then you shouldn't really be trusting glue records from 
the parent (delegating) zone, should you?

	I mean, you have to have them in order to break the Catch-22, but 
it is my understanding that you should treat them as untrusted and 
re-verify them from the authoritative nameservers (if you really care 
about that sort of thing).

   These are my opinions -- not to be taken as official Skynet policy
