As Thomas Gleixner spotted, it's rather horrible racy: - We can miss almost a full tick, so need to compensate by 1 jiffy. - We need to re-check the condition when having timed-out, since a the last check could have been before the timeout expired. E.g. when we've been preempted or a long irq happened.
