  From  WordNet  r  1.6  [wn]: 
 
  trampoline 
  n  :  strong  canvas  attached  with  springs  to  a  metal  frame  and 
  used  for  tumbling 
 
  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  trampoline  n.  An  incredibly  {hairy}  technique,  found  in  some 
  {HLL}  and  program-overlay  implementations  (e.g.,  on  the  Macintosh),  that 
  involves  on-the-fly  generation  of  small  executable  (and,  likely  as  not 
  self-modifying)  code  objects  to  do  indirection  between  code  sections. 
  Under  BSD  and  possibly  in  other  Unixes,  trampoline  code  is  used  to 
  transfer  control  from  the  kernel  back  to  user  mode  when  a  signal  (which 
  has  had  a  handler  installed)  is  sent  to  a  process.  These  pieces  of  {live 
  data}  are  called  `trampolines'.  Trampolines  are  notoriously  difficult  to 
  understand  in  action  in  fact  it  is  said  by  those  who  use  this  term  that 
  the  trampoline  that  doesn't  bend  your  brain  is  not  the  true  trampoline.
