= H =
hyperspace /hi:'per-spays/ n.
A memory location that is
far away from where the program counter should be pointing,
especially a place that is inaccessible because it is not even
mapped in by the virtual-memory system. "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.
