    OK, so can the suspend blocker then become just:

    # Block suspend while idle, system stays running
    # echo default > /sys/power/policy

    and the when it's OK to suspend:

    # Allow suspend while idle, system suspends when it hits kernel idle loop
    # echo opportunistic > /sys/power/policy

    or do you still need something more to ensure the data gets into your
    app and be handled?

    The part I really don't like is the idea of patching all over the drivers
    and userspace for the wakelocks/suspendblocks.

    Regards,

    Tony
