    Well, I don't own any android devices, but If I read this all
    correctly, an app can request the permission to grab an suspend blocker
    at installation time. ("This application is requesting permission to
    keep the device from sleeping, thus possibly reducing your battery
    time. Are you shure you want to continue? [Yes,No]")

    every app grabbing a suspend blocker is showing
    up in a "these programs stop suspend" kind of battery-app and are thus
    well accounted for. _And the user knows who to blame_.

    Maybe this is implemented via fs-permissions? Anyway, I'm shure,
    that the access control uses a well established method. :)

    Cheers,
    Flo
