This is nothing other than complete rubbish. FUD. No TCP Wrappers
implementation I have ever seen assumes what you've said. They all agree
with Jim. I know what you think because we've had this argument before,
but the above is just crap. I know you think it's correct to do it, that's
fine, but trying to scare someone into doing it by patent lies is just
ridiculous.
