FWIW, here are the beacons from my APs as received by iwn. (timestamps
replaced with xx to reduce the output after piping through uniq).

I was quite impressed by this:
$ sudo ping -c50000 -q -s800 -f 10.15.5.1
PING 10.15.5.1 (10.15.5.1): 800 data bytes
50000 packets transmitted, 50000 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 0.950/1.395/10.145/0.311 ms
So the only new issue I have with this diff is with manual scans (as
I mentioned before, but now with logs) - the scan runs and ifconfig
displays the expected output (at the point around where 'scan finished'
is logged, marked with > in the paste below), the radio status LED
remains flashing (expected as there's nothing to change the LED state
until it associates), it keeps logging 'received beacon', and won't
reassociate.
"ifconfig iwn0 -chan" clears this and lets me re-associate (re-inits
the device; ifconfig down+up clears it as well but -chan is less
disruptive as dhclient stays running that way). So I do have a usable
workaround.
I'm not quite sure what's different between the automatic scans when
looking for a network to associate with, and the manually triggered ones..
