If you have aio, the the NIC and the guest proceed in parallel.  If the 
guest is faster (likely), then when it sends the next packet it will see 
that interrupts are disabled and not notify again.  Once aio complete we 
can recheck the queue; if it's empty we reenable notifications.  If 
there's still stuff in it we submit it with notifications disabled.
