Natd doesn't use select if you use alias address instead of interface
name. In this case there is just simple recvfrom - sendto loop.
The select is there currently mostly to get information from routing
socket which is needed on DHCP / PPP environments. There
was also second purpose - to check space on output socket -
but it has been found unnecessary recently and I think it
was removed from -current, at least.
