    This really has nothing to do with modern day computing or modern day
    computers, and certainly has nothing to do with the problem at hand.

    Well do I remember cory.berkeley.edu, a poor Vax 780 at the time which 
    got driven into the ground nearly every day.  The machine blew up at
    least once or twice a week, but it was never due to running out of swap.
