It could be that you have a neighbor that will never deliver a packet sequence number, so 9.3 will never apply. Because I am not sure if packet (9.3) or message (9.4) processing is done first, I make sure to overwrite the data in the current element of the queue in 9.3 when I discover the packet sequence number.
