Finally!

I updated to newest git+patches (git version 1.5.4.1.1353.g0d5dd), reset 
windowMemory to 512m and restarted the process:

$ /usr/bin/time git repack -a -d -f --window=250 --depth=250
Counting objects: 2477715, done.
Compressing objects: 100% (2411764/2411764), done.
Writing objects: 100% (2477715/2477715), done.
Total 2477715 (delta 1876242), reused 0 (delta 0)
21733.55user 175.32system 6:10:37elapsed 98%CPU (0avgtext+0avgdata 
0maxresident)k
0inputs+0outputs (81921major+63880453minor)pagefaults 0swaps

A little over 6 hours, with one core (of the four available).  Not bad, I 
say.

The result is:

$ ls -la objects/pack/pack-e4dc6da0a10888ec4345490575efc587b7523b45.pack
-rwxrwxrwx 1 root root 1638490531 2008-02-14 17:51 
objects/pack/pack-e4dc6da0a10888ec4345490575efc587b7523b45.pack

1.6G looks much better than 2.4G, wouldn't you say?  Jan, if you want it, 
please give me a place to upload it to.

Ciao,
Dscho
