  34         This program takes the palindrome below and checks if it's
  35         a palindrome or not. It will hopefully exhibit an interesting
  36         page fault pattern.
  37 
  38         The palindrome was taken from 
  39 
  40         http://www.cs.brown.edu/people/nfp/palindrome.html
  41 
  42         This is not large enough to really stress the VM system, but
  43         might be useful for testing in the early stages of the VM
  44         assignment.
