It depends on the application;  netscape may use fixed CPU time, but other
programs do not.  Executor (for one), an emulator, will eat 40%-80% CPU time
by default if rc5 is left on idle.  Other real-time applications, say many
games, will eat as much CPU time as possible to generate as many frames /sec
as possible.  I can live with 40 fps instead of 60.. <G>
