Comment:

 looking at the log, i believe this is working as designed:  the laptop
 doesn't sleep (for long) because its woken by the ping activity.

 if there's an issue here, it's "why did the screen ever get a chance to
 dim?", since when the laptop woke at 14:06:48, it had been asleep for a
 full 165 seconds.  presumably the ping had been running all that time, and
 the wakeup conditions were set correctly.  this happens again at 14:11:15.
 (since the screen was already dimmed the first time, nothing visible
 happened the second time.)

 i wonder what happens if libertas gets a packet after the wakeup options
 have been set, but before the laptop has slept?

 back to the original topic of the Summary:  it's not clear what the right
 thing to do is.  there's network activity, so the laptop should stay
 alive, right?  we probably do want the screen to at least dim (and it's
 not clearly why that was able to happen), but if it were to blank, then
 we'd stop waking due to packets (at least, as soon as that by-popular-
 demand feature hits a release).  would that be the correct?  isn't the
 point that network activity should keep us alive?
