   | login via xdm
   | fire up xterm
   | su
   | wpa_supplicant -B -i iwn0 -c...
   | dhcpcd -L4 iwn0
 
 When you exit xdm (or the kernel) will do a session reset, and kill everything
 running in that same session (dhcpcd probably protects itself, I don't think
 wpa_supplicant does that).
 
   | open a terminal (ctl-alt-f1), login as root, and observe that iwn0 is down.
   | ifconfig iwn0 up
   | and all is well - the connection becomes active and a lease is acquired with no further intervention.
 
 Start wpa_supplicant (and dhcpcd) from /etc/rc rather than by hand.   You can
 run wpa_gui (from pkgsrc) in the xdm session if you need (or want) to interact
 with wpa_supplicant to get the link up - it isn't needed that wpa_supplicant bring
 up the link from rc.d,  just that it be started from there rather than from the xdm
 session.
