Andrea, you're *this* close to going to my list of people who it is not
worth reading email from, and where it's better for everybody involved if
I just teach my spam-filter about it.

That code was CRAP.

That code was crap whether it's used once, or whether it's used a million
times. Stop making excuses for it just because it's not performance-
critical.

So give it up already. I told you what the non-crap solution was. It's
simpler, faster, and is about two lines of code compared to the crappy
version (which was what - 200 lines of crap with a big comment on top of
it just to explain the idiocy?).

So until you can understand the better solution, don't even bother
emailing me, ok? Because the next email I get from you that shows the
intelligence level of a gnat, I'll just give up and put you in a
spam-filter.

Because my IQ goes down just from reading your mails. I can't afford to
continue.

Linus
