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."
