    It's not as high a priority as Li's bug fix (which may be a good
    candidate for 2.6.25.1) but for the future I think I'll implement this
    distinguished css_set pointer for tasks that have finished
    cgroup_exit(), since I think it will make the similar synchronization
    in attach_task() cleaner, as well as cgroup_enable_task_cg_list().
