Understood. But surely delegating cgroup.threads is effectively meaningless when delegating a "domain" cgroup tree? (Obviously it's not harmful to delegate the the cgroup.threads file in this case; it's just not useful to do so.) > 2. I haven't thought much about delegating a sub-protion of a threaded > subtree.
