This still looks like the wrong tool: Packets that can't be delivered
are queued. So we need to flush the queue and clear the blocked delivery
there. qemu_flush_queued_packets appears more appropriate for this.

Conceptually, the backend should be responsible for kicking the iothread
as needed.

as i understand the code, the backend _is_ the iothread, and it is
sleeping when the frontend becomes able to receive again.
