dns-01.ns.aol.com, for example, is in the .com servers' bailiwick, so we
can follow a referral from the .com servers to the aol.com servers. See
http://cr.yp.to/djbdns/notes.html for further background.
As for your suggestion: Yes, we can eliminate the reliability problems
caused by gluelessness, without introducing security problems, by
(1) having the server provide the A for every NS and
(2) having the cache save the A only in the context of that NS.
This is (aside from the unnecessarily difficult parsing) functionally
identical to putting addresses directly into NS records, which is my
suggested fix. Applying the same fix to A6 produces AAAA.
