....this can be deduced from the current status of all processes. Thus, whenever any process is running or ready to run, the processor should not be turned off; when all processes are blocked, the processor should be turned off [34 36] Examples of operating systems using this strategy are Windows [37, 38] and UNIX. MacOS, however, uses a different strategy, perhaps because its strategy was designed when processors did suffer side effects from turning off. It uses an inactivity threshold, as is commonly used for hard disk power management. The processor is shut off when there have been no disk ....

.... it makes no attempt to police processes that make unfair processor time requests; in fact, one recognized problem with its power management is that if a single process requests events using PeekMessage rather than GetMessage or WaitMessage, then processor power management cannot take place [2, 11]. This problem is exactly the sort that the greediness technique was designed to alleviate, so we may find that, as we demonstrated for the MacOS, the effectiveness of the basic strategy is greatly improved by the use of such a technique. We would like to see the work described here continued in ....
