Ok, but still the important thing isn't the kick per se, but the
resulting completetion. Can we do interrupt driven reclamation? Some
of those virtio_net emails I saw kicking around earlier today implied
buffers are reclaimed on the next xmit (e.g. polling) which violates the
netif rules for avoiding deadlock. I suppose that could have just been
an implementation decision....but I remember wondering how reaping would
work when virtio first came out.
