Properly designed the stack protection, array bounds checking and
pointer validating routines can be put into queue slots that would
otherwise go idle on modern cpus. One might even fit it in along with
other instructions and not even blow up the programm size with every
check.
For most programm it realy doesn't hurt and for everything thats
dangerous (suid, servers, other root stuff) making it the default
might be the right[tm] way. Compared to the binaries now you probably
waste as much on the checks as you save if you optimize for your cpu.
