Yeah I guess I should really do that, and you're right it would
work nicely for this.

Actually I have some code but it is not quite as nice as I'd like.
The problem is that we have the generic file fault handler, but not
a generic page mkwrite handler. So we still need some kind of
page_mkwrite aop which the file fault handler can then call if it
exists. It isn't a big problem AFAIKS, but just a bit irritating.
