No, I'm using only one IP address for the bridged pair of NICs. (The
IP address is assigned via "ifconfig rl0".)

I'll have to redo my earlier tests and send the results sometime later.

after several minutes, a reply did get sent out, but I have no idea why
this happened or what provoked the machine to finally get around to
sending an ARP reply.

OK. See below.
