I definitely agree, I don't think we want to go away from the page table
as being the abstraction :-) But I'm wondering if we can do a little bit
better with the accessors to those page tables.

BTW. am I the only one to have got one copy of David's reply (that I'm
quoting) coming with a From: Nick Piggin in the headers ? (apparently
coming from kvack).

Cheers,
Ben.
