If I read this correctly, pcap will sometimes wait
forever until a packet appears, which I don't actually
mind because it's actually the behaviour that I'm
expecting.  What is really odd is that even when
packets ARE arriving, pcap_loop just sits there, lets
the packets pile up, and then shows all the messages
at once... then it blocks again for a while, even as I
send messages from the other computer, just to show
them all at once again, and so on...

I'm actually going multithreaded, but I'd expect a
packet to show up immediately, so I can process it and
perform the routing in a timely manner, rather than
delivering a packet a minute after it was sent.

Thank you very much!
