Using notify_on_release doesn't make any guarantees that the notification, or the action based on that notification, will occur before the cgroup becomes busy again. An rmdir() on a busy cgroup is perfectly safe, it just fails with -EBUSY. I'd just like to avoid making active control file fds trigger than failure mode.
