I think you'll still see it in spam zombies, some of which have the
DNS info
pre-loaded into them in order to avoid split-horizon anti-spam
techniques.
Not much we can do about that until we get sufficient backbone to deal
with the zombie problem and its software enablers.
Actually, I think the fact Zombies do not honor TTLs is a feature. :)
