Just got on this thing (perhaps very belatedly) - root server trouble?

What do you think happens to the nameservers on the net when they're asked
for a domain that doesn't have functional servers, and they sit and churn
trying to resolve the names?
BTW, churn is the right word. Its taking anywhere from 5-10 *seconds* to
come back as NXDOMAIN on each request for those that fail to resolve, and
this is from the IANA roots.
This IS a functional problem - and worse, all those non-existant zones and
the VM churn they generate on the COM TLD servers is probably the REASON
that we're looking at this kind of horrid performance!
