Ok, I looked more deeply into this today. It seems that the problem lies in the
"allow-hotplug eth0" option vs. "auto eth0".
Initially somehow (probably because stop didn't working at all with NM
installed) I blamed NM for the fact that "/etc/init.d/networking start" did not
result in dhclient3 not being ran again.

"/etc/init.d/networking stop" has zero effect.
