Hi all,

this is something Tony and I have been working on behind the curtains
recently. Here it is in a RFC form, it passes quick testing in kvm. Let
me send it out before I start hammering on it on a real machine.

More indepth info about what it is and what it does is in patch 1/3.

As always, comments and suggestions are most welcome.
