TLD nameservers that also cache?

	While it wouldn't help anyone who didn't implement the new code, 
I think I can safely say that if we had this feature in a more 
up-to-date version of BIND that we would implement that very quickly. 
So, at least we'd be okay.

	This is part of why I was thinking that this feature should be 
configurable, and to default at only reducing the questions to the 
root nameservers and to the gTLD & ccTLD nameservers (none of which 
should be caching anyway), and then from that level down go back to 
the old behaviour.

	Right, this gets back to the configurability of the behaviour -- 
you might want to completely turn it off in certain circumstances.

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