hyperspace

hyperspace: /hi'per-spays/ n.  A memory location that is
   *far* away from where the program counter should be pointing,
   often inaccessible because it is not even mapped in.  "Another
   core dump -- looks like the program jumped off to hyperspace
   somehow."  (Compare {jump off into never-never land}.)  This
   usage is from the SF notion of a spaceship jumping `into
   hyperspace', that is, taking a shortcut through higher-dimensional
   space -- in other words, bypassing this universe.  The variant
   `east hyperspace' is recorded among CMU and Bliss hackers.
