The ARP code is pretty stupid - it just sends out an ARP request and hopes to 
get a reply sometime. In the meantime, it would just keep sending ARP 
requests, and wouldn't even notice if it didn't get an ARP reply.

The ARP implementation is better suited for TCP, which times out after a 
while and gives up (and doesn't retransmit so ofter, either).
