with this patch, if you have appletalk support as a module, killing
atalkd and unloading the module will allow you to restart atalkd. if
you add a little patch to atalkd so that it uses SIOCATALKDIFADDR in
the same way that BSD uses SIOCDIFADDR, atalkd will take down its
interfaces properly when it dies as well.
