I first packaged the kernel patch for that in November last year.  I have 
since passed it on to Jonathan McDowell.  See

Wimps.  When in OS class I killed two major time-sharing machines (the main 
staff machine and the main student machine) on a Friday night.  The student 
machine was down for the entire weekend and caused dozens of students to be 
unable to complete their assignments on time.  ;)

I'd like to teach an OS class at uni.  I'd divide the class into two groups.  
One group of sys-admins the other hostile-users, then they change sides at 
half time.  It would be fun for everyone!
