    On that note, is there a good reason why the notify_on_release interface
    works the way it does? Wouldn't it be simpler if the cgroup simply
    provided a file on which a process (e.g. systemd) could block?

    I guess it's a little too late at this point considering the old
    mechanism will still need to be supported, but it seems like this would
    provide a slightly cheaper cleanup path. Just my (perhaps flawed) two
    pence.
