+ *   A third idle-detection option could be implement (but is not): when running
+ *   on the console display ($DISPLAY is `localhost`:0) and we're on a machine
+ *   where /dev/tty and /dev/mouse have reasonable last-modification times, we
+ *   could just stat those.  But the incremental benefit of implementing this
+ *   is really small, so forget I said anything.

  *   Debugging hints:
  *     - Have a second terminal handy.
  *     - Be careful where you set your breakpoints, you don't want this to
