Note that the current scheduler still schedules this job quite often even during something CPU intensive like a make -j. Ingo's O(1) scheduler has now changed this so that these jobs get an even smaller timeslice. So whilst not perfect, it's probably as close as you're going to get to a "schedule me when the system is idle" Depending on what your daemon is doing, you may be able to get it to block on a socket/fd or the likes which would be the perfect way to get the process to consume no cpu until the event occurs.
