I think this is one of several good reasons why moving to cpuidle would be
big win for XO-1.5  It solves the problem of managing wakeup timers, and
does it in a perfectly abstracted fashion, requiring no alterations to
userspace.  Adding wakeup timer management to "OHM" sounds like a big
pain, and yet another maintenance burden.
