Process scheduling is done whenever the currently running process either
blocks itself or reaches MAXSLICE clock-ticks, or a realtime process
(V.4) declares itself ready to run. MAXSLICE is usually set to 100
(i.e., process scheduling runs once a second) so that the maximum amount
of CPU time is devoted to user processes, or so says AT&T.
