Toggling kill switch on my lappy causes the driver powering my device 
(ipw2200) to stop functioning, it dissassociates from whatever network it was 
currently connected to, wpa_supplicant processes this event and it emits a 
DISCONNECTED event to its ctrl_interface where a listening process can act 
upon it. I use the wpa-roam mode, and it acts on this event by taking the 
interface down with respect to ifupdown...

You forgot to tell us how your wpa_supplicant is set up.
