+<h3 id="Notes"> Notes</h3> <p><code>duration</code> and <code>remaining</code> may point at the same object, which simplifies re-running the function after a signal.</p>
+<p>The actual sleep time may be longer than requested because it is rounded up to the timer granularity and because of scheduling and context switching overhead.</p>
