It is my understanding that the L4 memory management doesn't preclude
you from using a more traditionaly monolithic VM approach. By "recursive
pagers", I think you are referring to the notion of spreading the VM
work out among the threads, to handle requests close to where they came
from, right? It is a sort of "distributed VM" system.

I don't think anything prevents you from just naming the same thread as
the pager for all other threads, right?
