If you read either "Exploiting Software" pp. 57-65 or "Shellcoder's
Handbook" pp. 161-167, you'll have much less confidence in the /GS
switch. The sad truth is that using that switch can make it /easier/ to
exploit vulnerabilities. Maybe the next release of MSDev will improve
the /GS switch -- but who knows, really.
