Now, _that_ is strange.  Using 150 instead of 250 brings it down even 
quicker!

$ /usr/bin/time git repack -a -d -f --window=150 --depth=150
Counting objects: 2477715, done.
Compressing objects:  19% (481551/2411764)
Compressing objects:  19% (482333/2411764)
fatal: Out of memory, malloc failed411764)
Command exited with non-zero status 1
7118.37user 54.15system 2:01:44elapsed 98%CPU (0avgtext+0avgdata 
0maxresident)k
0inputs+0outputs (29834major+17122977minor)pagefaults 0swaps

(I hit the Return key twice during the time I suspected it would go out of 
memory, so it might have been really at 20%.)

Ideas?
