You've got one point here. As the cpumasks are inherited, you'd just
have to make sure that a user cannot escape his cpuset by e.g. not
allowing the mask to get bigger than the mask of the parent process
(which can be owned by root, thus unchangeable). The management of the
cpusets can then be taken over by a user space daemon.
