Doh! For some reason it had gotten into my head that "configure" (as opposed 
to "configure soft") was the sledgehammer appraoch to re-configuring bird 
(including downtime for any "affected" protocols). Doing just "configure" 
instead of "configure soft" seems to do the trick just fine indeed based on 
some quick tests.

Thanks for the nudge in the right direction!
