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.
