And then Xen will pin them for me recursively, or they will not be
pinned at all but just checked against having writable references? I
seem to have a problem when combining writable pagetables and the
traditional pinned ones in the same domain. The pagetables I inherit
from the domain builder need to be unpinned before I can use the pages
they reference for my own page tables, or I get complaints about trying
to create a writable linear p.t.
