Time Drifts With Delta Lists

• What they also teach in "Intro To OS 101", is that timers tend to drift.
• I.e, because we're not running on a real-time operating system, a sleep for X seconds may cause us to wake after X seconds + Y micro-seconds.
• If we had a delta-list of timers, and each timer wakes up slightly too late, then after several timer set-off events, we'll start collecting a noticeable delay.
