This "guiding principle" appears to be the primary reason why we've taken over a year to stabilise linux 2.0 and linux 2.2 and linux 2.4 ... or at least, too much of a focus on the first half of this guiding principle. ;)
We absolutely have to take care in avoiding the worst case scenarios, since statistics pretty much guarantee that somebody will run into nothing but that scenario ...
