I'm going to make a stab in the dark, but this also assumes that
nameservers don't cache translations, and by nameservers I mean
the ones on ISPs and localhosts around the world. This would
mean that a DoS would have to operate until the cache expired, by
which time the attacking hosts could have been filtered, or the root
nameservers could have been kicked.

As I've said previously, DDos wouldn't work particularly well,
because there's a lot of hosts to hit, and the root nameservers are
fairly well maintained. The next suggestion would be just a typical
memory leaky-thingy (I love technical terms) or something along
those lines to kill the named. This is also fairly difficult as the
primary nameservers run different nameds (as far as I know), and
so would require multiple applications to be flawed.

my first post, yay.
