I'm not sure if this is a bug to file against intel, or a bug for us to worry
about. The firmware crashed, taking me offline. Fortunately `service netif
restart` brought wireless back for a short time before I saw this in 
/var/log/messages:

Dec 10 10:47:05 kiwi kernel: iwn0: device timeout
Dec 10 10:48:35 kiwi kernel: iwn0: device timeout


The firmware crash itself:
