With the basic changes I described before, the  100 patch time only goes down
to 40s.  Certainly not fast enough to justify the changes.  In this case, the
bulk of the extra time comes from write-tree writing the index file, so I
split write-tree.c up into libwrite-tree.c, and created update-cache
--write-tree.

Hmm.  Are our index files too large, or is there some other factor?
I was considering using a chunked representation for *all* files (not just 
blobs), which would avoid the original 'trees must reference other trees 
or they become too large' issue -- and maybe the performance issue you're 
referring to, as well?
