Is there a reason you don't use the standard incantation of
ifconfig_wlan0="WPA DHCP" in /etc/rc.conf?

An alternative would be to manually do an "/etc/rc.d/netif stop wlan0"
or, even "ifconfig wlan0 down". I suspect that yanking the parent
process out from under the wpa_supplicant is causing a deadlock. (This
is a bug, but I have no idea how difficult it might be to fix.)
