hmm, I'm having trouble associating the "mapping" and a refcount of
some sort somewhere, any pointers?
See share_xen_page_with_guest() in arch/x86/mm.c. The refcnt is
dropped when
xenheap_pages field reduces to zero in
common/page_alloc.c:free_domheap_pages().
Hmm.. but the console page is a "domain page", no?
After looking at more code I convinced myself that a page not owned
by the domain but owned by another is "foreign".
