setgid() programs don't dump core, I think.  If they do, that is a
security hole, and should be fixed.  Non-problem.  General suggestion
(and this is not aimed just at Nate): Please think twice before trying
to shoot down somebody elses suggestion.  By shooting down changes, we
end up being very conservative - and if people get their suggestions
for good changes shot down, they are less likely to try again later.
Example: This tendency almost cost us our NAT code before - everybody
(by the authors impression) was shouting "you can't do that!" before
he'd written the code.
