I understand. There's one small problem. If you, for example, have
lots of aliases on your network interfaces (I mean, a lot), then
if you run named on this machine, it will complain:
Jun  2 16:49:08 sputnik named[993]: evSelectFD(dfd=256): Invalid argument

like this. (It was a bind8)
The same with bind4, with a slightly different message.
And this machine has only class C.

I was just trying to fix it.

Another problem is a busy IRC server. irc.best.net, for example, requires
FD_SETSIZE defined to 2048 at least.
