Comment:

 With autosuspend now enable-able in the GUI, this will cause clocks to
 start drifting out in the world.  The kernel should not lose track of big
 parts of a second on each suspend!

 I proposed a fix here: http://dev.laptop.org/ticket/3359#comment:3, based
 on my suspicion of what's going on (kernel is resetting its idea of the
 time based on the RTC, but the RTC
 only has 1-second precision even though it has high long-term accuracy.
 Fix: kernel should zero in on *when it ticks* to be more accurate than the
 current half a second.)
