I had considered this.  It's a little awkward since b/c of the dependence
on QEMU's async IO routines but it wouldn't be that bad.

At this point, it probably makes most sense to communicate the linear
offsets within the framebuffer that are dirty instead of computing a rect.
 Since the QEMU VNC code already does rectangle finding and maintains
 dirty tile bitmap, we don't really have to attempt to find the rect in
the frontend at all.

Anthony Liguori
