   Wonder what would happen if you did something like moving core on top
   of /.cshrc or /.login?

   how bout ln core .cshrc?

   how bout:  cp /dev/zero /  (is that possible i wonder?)
              ln zero .cshrc  Sounds particulary nasty. 

   This is only a speculation, not an exhibition so please please --   
   no wagering!
