Oh, wait, now I understand the problem -- the NS records in the root only 
provide the names of the root servers.  There's glue with the 
root-servers.net A and AAAA records but they're unsigned.

I still think that a local root mirror is likely to be less of a kludge 
than whatever else we come up with to validate ADoT roots.
