Are you saying that PIDs will be allocated by the root server (or some
other privileged) server, not by the proc server? (As it's not
mandatory for tasks to register with any proc server, and definitely
not with a privileged one).
Must a subhurd have a different "subsystem id" than its parent? I hope
not, since allocation of a new subsystem id sounds like a privileged
operation, and creating a subhurd shouldn't require any special
privileges.
