/* halt.c
 *      Simple program to test whether running a user program works.
 *      
 *      Just do a "syscall" that shuts down the OS.
 *
 *      NOTE: for some reason, user programs with global data structures 
 *      sometimes haven't worked in the Nachos environment.  So be careful
 *      out there!  One option is to allocate data structures as 
 *      automatics within a procedure, but if you do this, you have to
 *      be careful to allocate a big enough stack to hold the automatics!
