It's nice to find out that I was right about this. The I/O code that I'm
on banishes wildcard addresses altogether, but there are issues about
deciding whether or not the destination address was a unicasy, broadcast
or multicast address. I need to sort that out still. In addition I needed to
write some code to figure out which socket should receive the multicast
packets. It's all in progress right now but the result will be reliable
