are 9p mesages really the right vehicle for this? 9p messages
provides a serialized and in a standard byte order. this requires
byte reordering (on intel) and copying. but are these really needed?
the guest and host are on the same platform, so the guest can
pass pointers to the host. for the same reason, integers don't need
reformatting.
modern devices usually dma directly, so the host may never need
to touch the pointed-to memory.
perhaps using Fcall structures directly would be more efficient?
That's one of the options. We are probably going to start with
serialized content (no copying of the data though) and if it is too
slow, we won't do serialization.
