Yes, I think it makes sense.  Moving this to a separate process isn't
that useful for virtio-input, other devices like virtio-gpu will benefit
much more from it from a security and performance point of view.  It
still is useful for (a) testing the vhost-user infrastructure and (b) as
relatively simple example.
