First, this *must* be a compile-time constant. Second, this is really only a 
way to turn up stupid bugs such as calling 'msleep(1000);'. I don't see any 
point in having a perfectly value here. Besides, the kernel might be able to 
properly sleep for periods short than the scheduler interval, so there is no 
way to be truly accurate.
