I don't know what "killall dhclient;ifdown eth0;ifup eth0" method is but I 
never found that necessary.  You should be able to bring the iface down, 
then edit interfaces file, then bring it up with the new config.  I don't 
think restarting networking service is what you want, it does not do the 
same thing as the old /etc/init.d/networking restart command did.

Alternately I have used separate iface names for each config and used 
something like ifup wlan0=cfg_static ifup wlan0=cfg_dhcp 
depending on which I wanted.


iface cfg_static inet dhcp
     address 192.168.1.109
iface cfg_dhcp inet dhcp

good luck
