The series [1] I just sent helps reduce pack-objects memory footprint a bit. But even then it's still a huge memory hog. So this patch makes a special treatment for gc --auto: avoid it completely.
The trick here is not new (pinning the largest pack with a .keep file). It's just never done automatically. I think this is a good thing to do, provided that gc --auto estimates memory usage more or less correct. And "git gc --auto" should run even on weak machines because it's part of regular repo maintenance. You can't tell people "You can't work on linux-2.6.git repository because your machine has too little memory". The only thing left I think I should do is to use an external rev-list to free up some more memory. But let's see how the first patch goes first (documents and tests are missing, I know).
