After the suggestions in this thread I tried to experiment with the --window 
and --depth options of git-repack, and indeed, there are still reserves.

So far I'm at 2G (saved 500M), unfortunately the aggressive values like 
--window=250 --depth=250 that someone mentioned here cause out-of-memory on a 
machine with 8G :-(  If there's anybody brave enough here to try as well, I'd 
be grateful.  Maybe it would be also interesting to _exactly_ locate what 
causes the oom, and eg. exclude the object from the pack if possible.

The tree is available here:

git clone git://o3-build.services.openoffice.org/git/ooo.git
git clone http://o3-build.services.openoffice.org/~svn/ooo.git (the same over 
http://)

Thank you in advance!

Regards,
Jan
