sleep

   1.  [techspeak] To relinquish a claim (of a process on a multitasking
   system)  for service; to indicate to the scheduler that a process may
   be  deactivated  until  some  given  event occurs or a specified time
   delay elapses.

   2.  In  jargon,  used very similarly to v. {block}; also in sleep on,
   syn.:  with  block  on.  Often  used to indicate that the speaker has
   relinquished a demand for resources until some (possibly unspecified)
   external event: "They can't get the fix I've been asking for into the
   next  release,  so  I'm  going to sleep on it until the release, then
   start hassling them again."
