I'm curious. As a non-C programmer, is there ever a reason to
*not* do bounds checking? (I mean outside of intensely performance
critical applications like realtime control systems (which would
probably be better in assembly anyway). I don't count an OS or a
web browser as 'intensely performance critical'; they are, rather,
'intensely security and stability critical').

Thanks!
