If a message isn't being sent when you unplug the cable that's a bug,
and it's either the driver or the hardware.  Most likely the driver,
particularly in the case of bfe(4) which isn't all that common.  I'd
suggest filing a bug report against the nic driver.

So your ifconfig_<wireless> variable is set to "DHCP" and dhclient isn't
appearing and disappearing as it should?  I'll have to look into that.
Are you running with the iwi driver?  My laptop has one of those so I
can test it.
