    Well if your hardware runs off-while-idle or even just
    retention-while-idle, then the basic shell works just fine waking up
    every few seconds or so.

    Then you could keep init/shell/suspend policy deamon running until
    it's time to suspend the whole device. To cut down runaway timers,
    you could already freeze the desktop/GUI/whatever earlier.

    Regards,

    Tony
