Thanks Liz,
I was pretty sure there'd be something like that possible, but do you know how your example could be executed so that it affects my program _while its running_?

I assume I am protected by *NIX protected memory... but I wonder if there is some debug mode for Perl that lets one inspect running code...or poke at a Perl process...? Cheers,
Craig.
PS My idea is getting some function creep, or worse, creep creep. However, to compromise the running process would require your hack above being able to affect my running process. I hope you haven't lost patience with this idea. The question then becomes "does this fangled idea really add any more security than tripwire etc?"
