This could mislead readers to think that a cgroup is empty when it's not. Fixed by making PROCS iterator include dead tasks. I made a couple mistakes making this change and this pull request contains a couple follow-up patches. - When cpusets run out of online cpus, it updates cpusmasks of member tasks in bizarre ways.

Because of a misunderstanding/copy-paste error inside runc (see https://github.com/opencontainers/runc/pull/2065), it tried accessing the cgroup control file of a 64kB HugePage using "hugetlb.64kB._____" instead of the correct "hugetlb.64KB._____". Adding a new example will make it clear how sizes smaller than 1MB are handled.
