sleep

sleep vi.  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."
