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.
