Subject: Coming soon: CPU fix for buffer overflows

leading to cruddier and more bloated code and yet more security 
problems..won't it be interesting if these hardware technologies have 
"overflows" of their own..:)

My "foundation" verse:
Isaiah 54:17 No weapon that is formed against thee shall prosper; and 
every tongue that shall rise against thee in judgment thou shalt 
condemn. This is the heritage of the servants of the LORD, and their 
righteousness is of me, saith the LORD.
