I don't like this even more.

Pid namespaces are hierarchical _and_ anonymous, so simply
set of numbers doesn't describe the final object.

struct pid isn't special, it's just another invariant if you like
as far as C/R is concerned, but system call is made special wrt pids.

What will be in an image? I hope "struct kstate_image_pid" with several
numbers and with references to such object from other places, so it
seems natural to do alloc_pid() with needed numbers and that attach new
shiny pid to where needed. But this clone_pid is only for task_struct's pids.
