Yup, that is exactly what I was thinking of. So darcs would only need to 
calculate dependencies for the patches that are not in the latest tag, which 
is usually orders of magnitude less than the whole repo. It is not perfect, 
of course, but it would still be a noticeable improvement for usability.
