sleep
vi. 1. [techspeak] On a timesharing system, a process that
relinquishes its claim on the scheduler until some given event
occurs or a specified time delay elapses is said to `go to
sleep'. 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."
