This will permit expansion of the api to cover cpu masks for other objects identifiable with an id_t integer. For example, IRQs and Jails may be coming soon. - The root set 0 contains all valid cpus. All thread initially belong to cpuset 1. This permits migrating all threads off of certain cpus to reserve them for special applications.

No, but thanks for noticing. I need to discuss something with peter first.
