One more curiousity is how often a timer routine is called & how often scheduling code? It may be configurable interval as well, but then whats default value. I guess timer is called more frequently & call to scheduling routine is made less frquently and is called from timer itself. Can I get pointer to some reference where I will get to know how exactly this mechanism works. May be digging through code will be expensive option so I want to avoid it for a moment.
Your best bet is to study the code. The scheduler code is fairly readable. IIRC, the accounting code happens in two parts -- every 10ms, measurements are made, but only every 30ms the measurements are used to update accounting information.
