Here's another issue to consider:

This code in vc-dired-hook: 

         ;; ordinary file
         ((and (vc-backend filename)
                (not (and vc-dired-terse-mode
                           (vc-up-to-date-p filename))))
          (vc-dired-reformat-line (vc-call dired-state-info filename))
          (forward-line 1))

Is the vc-backend call necessary? It ends up calling vc-registered and
that can be expensive for the backends that run a program to determine
that. The -dir-state method computes the state for most (all?)
files... 
I don't understand this code very well, but if it can be simplified,
it might result in a significant speedup for vc-dired.

Can you please take a look? 

Thanks
