Now this I don't think is a good idea.

If we applied this patch our mailboxes would overflow with complaints
from people who can't afford the lookups but do a lot of CGI suddenly
finding their servers grind to a halt for no apparent reason.

If scripts need the hostname they can look it up themselves 
(1 line of perl for example).

This is a CGI issue, not an Apache one.
