I sent Jamie a request, and he sent me the code (thanks!) and I read it and
indeed it's not real different from a lot of other synflooders out there (but
it sure is the cleanest implementation I've seen).
Someone from ISC ran it against F.ROOT-SERVERS.NET for a while, and while the
gross CPU usage went up, the rate of DNS response generation did not change.
Thus we concluded that a 4-CPU Alpha ES40 running Tru64 5.0 is "safe".
