Maybe send_invalidate_req() could be triggerd by the pager in some way?
Andres sent a patch to move from domctl to memop. Maybe the paging part
of it could be extended to issue another command which just calls
send_invalidate_req(). If thats possible, then I assume the upstream
qemu does not need changing as well.
