I have to agree with David here - although there's many failure modes if
a security-relevant program wants to talk to the network, they're all already
prone to stuffage by an attacker.

Biggest danger is probably programs that rashly assume that 127.0.0.1 is
reachable.  Seen a lot of *that* in my day (no, don't ask how I found out ;)
