Bob, it's something I've been worrying about for a while; in Mchip seminars
they tell me to "think robust", and always reinitialize in all sorts of
different situations, but it really troubles me because if ANY register is
corrupt then you must assume they ALL might be corrupt, right?  I'd like to
learn more about how they do it in the auto world, where there's bootloads
of trauma circulating around...
