The problem is, that it get's pretty slow if you don't do a time
cut-off... i don't know the complexity but i guess it's linear in
(number of files) * (number of commits) * (avg size of diffs) ... 
(if you compute the diffstat) 

What I'll probably try as soon as I have another few hours to spare
for get_maintainer.pl, is to implement a fall back to older history if
the data basis is not stable enough.

Yes.  I guess, my current version could use an staggered approach where
it does more digging if the results are too volatile... but first
try to be fast ...
