Having had debugging DHCP, it might be useful to know that Ubuntu
(and so probably Debian) execute dhclient from the ifup-related scripts depending on
the contents of /etc/network/interfaces. It's not a top-level init script.

Figured this might save you a moment or two grepping for a deeper understanding.

There was nothing on those ports, but somehow I had a lease. I rebooted, and
new dhclient is running. Perhaps something had crashed it, but I can't
imagine what.

Anyway, I have my answer. Thanks for the help.
