This all nice in theory, but are you sure that every sleep() causes setting of hardware timer? In every OS? In every minor version of OS even? If not (and I'm pretty sure it's not so), then you need to add more details. All about how scheduler works. Or this precise talk on what happen after time is up would just mislead people. Aside from the fact that sometime after time is up thread would become runnable again (which is really obvious, no?) there is nothing to say. -- Nick Voronin <elfy...@gmail.com>
