It would be even better to simply have the rule: - child gets almost no points at startup - but when a parent does a "waitpid()" call and blocks, it will spread out its points to the childred (the "vfork()" blocking is another case that is really the same). This is a very special kind of "priority inversion" logic: you give higher priority to the things you wait for. Not because of holding any locks, but simply because a blockign waitpid really is a damn big hint that "ok, the child now works for the parent".
