I've renewed this again, with some comments from HPA. I've tried to
keep the new patches separate, so you can see the changes since we
last discussed this (and so it's easy to back it out if we decide it's
insane).
I haven't even looked at the QEMU side so this is completely untested.
Comments gratefully received!
Rusty.
