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.
