+  Title:       TICKLESS OS
+  Description: On a side note, I have thought about a tick-less timer for the OS
+               for a long time.  Basically we could replace the periodic system
+               timer interrupt with a one-shot interval timer programmed for the
+               next interesting event time.  That is one way to both reduce the
+               timer interrupt overhead and also to increase the accuracy of
+               delays.
