   note: sleep is attended by a relaxation of the muscles, and
         the absence of voluntary activity for any rational
         objects or purpose. the pulse is slower, the
         respiratory movements fewer in number but more
         profound, and there is less blood in the cerebral
         vessels. it is susceptible of greater or less intensity
         or completeness in its control of the powers.

[7] : Jargon File (4.3.1, 29 Jun 2001)

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."

sleep
     
        1.  or "block" when a
        process on a multitasking system asks the scheduler to
        deactivate it until some given external event e.g. an
        interrupt or a specified time delay occurs.
     
        the alternative is to poll or "busy wait" for the event
        but this uses processing power.
     
        also used in the phrase "sleep on" or "block on" some
        external event, meaning to wait for it.
     
        e.g. the unix command of the same name which pauses the
        current process for a given number of seconds.
     
        2.  to go into partial deactivation to save power.
