Sounds nice, but firstly we need to figure out this case, and then we
can do adding/removing/whatever
Without fixing that, it would be possible to see
adding/removing/whatever twice.
How to reproduce:
1) put debug info into rc.d/wpa_supplicant, a «toto» looks very
informative!

2) then: service netif restart
3) then: cat /tmp/toto, how many totos do you see?
4) if you are lucky like I am, you can even observe something like this:
root 15038 0.0 0.1 21596 6100 - Ss 8:42pm
0:00.16 /usr/sbin/wpa_supplicant -s -B -i wlan0
-c /etc/wpa_supplicant.conf -D bsd -P /var/run/wpa_supplicant/wlan0.pid
root 15077 0.0 0.1 21596 6112 - Ss 8:42pm
0:00.12 /usr/sbin/wpa_supplicant -s -B -i wlan0
-c /etc/wpa_supplicant.conf -D bsd -P /var/run/wpa_supplicant/wlan0.pid
What was happened? netif tries to setup wlan0 (clone, wpa, dhcp, etc),
when wlan0 interface occurs, devd runs another copy of netif.
