There is some client-server spaghetti for controlling the new ISC DHCP
stuff that you could probably set up to kick the client without
restarting it, but this is probably easier.

If you are using IPv6 then you need some way to kick rtsold so you
don't have to wait as long for the interface to come back.  maybe
'ifconfig wi0 down up' or something?  I haven't been using IPv6 very
long.
