So you're saying that a task can only be in a single system-wide container. My patch provides multiple potentially-independent ways of dividing up the tasks on the system - if the "container" is the set of all divisions that the process is in, what's an appropriate term for the sub-units? > > You are calling something that is on par with a namespace a container.

That assumes the viewpoint that your terminology is "correct" and other people's needs "fixing". :-) But as I've said I'm not particularly wedded to the term "container" if that really turned out to be what's blocking acceptance from people like Andrew or Linus. Do you have a suggestion for a better name? To me, "process container" seems like the ideal name, since it's an abstraction that "contains" processes and associates them with some (subsystem-provided) state. Paul
