Shouldn't a decent OS scrub RAM and disk sectors before allocating

I have been out of the loop for quite a while but my strongly held
belief is that such scrubbing would be an enormous (and intolerable)
overhead ...


It must be quite a while.  Unix systems have routinely cleared the RAM
and disk allocated to programs since the earliest days.


When you say "clear the disk allocated to programs" what do you mean
exactly?


Is that like "sudo rm -rf /bin" ?

;P
