wormhole

wormhole /werm'hohl/ n.  [from the `wormhole'
   singularities hypothesized in some versions of General Relativity
   theory] 1. obs.  A location in a monitor which contains the
   address of a routine, with the specific intent of making it easy to
   substitute a different routine.  This term is now obsolescent;
   modern operating systems use clusters of wormholes extensively (for
   modularization of I/O handling in particular, as in the UNIX
   device-driver organization) but the preferred techspeak for these
   clusters is `device tables', `jump tables' or `capability
   tables'.  2. [Amateur Packet Radio] A network path using a
   commercial satellite link to join two or more amateur VHF networks.
   So called because traffic routed through a wormhole leaves and
   re-enters the amateur network over great distances with usually
   little clue in the message routing header as to how it got from one
   relay to the other. Compare {gopher hole} (sense 2).
