If you run dhclient by hand, you have to stop it by hand.  ifdown will only stop
dhclient instances started by ifup because the PIDs are recorded.  You cannot
run more than one dhclient per interface at a time.  If you have a multihomed
host, you need to specify the interface name to run multiple instances per

dhclient eth0
dhclient eth1
... and so on
