ifconfig -a shows:
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232
index 1
inet 127.0.0.1 netmask ff000000

I dtraced the timeout situation (in background with output to file), and called
'wificonfig -i pcwl1 scan' (this produces a timeout message) few times.
Dtrace produced the following result:
