That was the point of my "canary" comment.  It was a bit
cryptic... one way of guarding againsty stack-smashing (memory)
attacks is by adding a special marker at the end of memory.  If
that marker ever gets modified, then you know that something
altered memory that shouldn't have been altered, so there's either
a serious bug or a hostile attack.

ok, granted, the ability to modify memory that you shouldn't be
able to modify is itself a serious bug.  But you get the point.
:)

The "meow... yum" comment was about a cat eating the canary, since
I like cats.


This would be a fantasic job for a Frog, BTW.
