Yes, we should consider whether or not we should rescan the interfaces 
when we get these kinds of errors so that ntpd can recover from a change 
in IP address. That's certainly a good idea. We'd need to have a check 
so that we don't rescan too frequently otherwise we'd be spending all of 
our time rescanning.
