If your system is idle and your hardware supports off-while-idle,
then that really does not matter. There's not much of a difference
in power savings, we're already talking over 10 days on batteries
with just off-while-idle on omaps.

If your userspace keeps polling and has runaway timers, then you
could suspend it's parent process to idle the system?
