The professor (insert big, big grin and wink here) answers:
Didn't want it to loop forever, just a day or two. There are 2800+
files in /usr/bin, so 1440 minutes/day * 2 = 2880. It works and it's
utterly trivial. Also, this was a "quick and dirty" loop. I'm
interested in the numbers. Is Fedora in fact stressing our disks? How
does this compare to other OSes? Etc., etc.
