I'm working on a project to checkpoint and restart processes. Obviously, after a
process dies, and is "transparently" restarted, it might get confused because
its pid changed. (This is one of many issues, but I'm starting with pids)

I don't want to change the kernel's internal idea of pids, but I would like to
have a new pid namespace which a process can see. This means finding all the
places where the kernel returns a pid to userspace, and returning something
different. The following patch series implements a very simple mechanism for
doing that.

I know the stuff in the end is relative junk (just for testing), but does
anybody see a good reason that we can't start merging something resembling the
first couple patches?
