Wouldn't it be less invasive to change procps so that doing

ps <pid1> <pid2> ...

only actually looks at /proc/<pid1>, /proc/<pid2>, etc, rather than
looking at all of them and then throwing away any that aren't in the
supplied list?

Then you could do what you want with ps $(cat /dev/cgroup/xxxx/yyy/tasks)
