I have created a 100 GB swap file and ran git gc again.
It ate my 8 GB of RAM + 38 GB of swap. It ended successfully:

    vincent@berlioz:~/photos2$ time git gc --aggressive

Yet the following git annex sync didn't do better than previous ones and took 285 minutes to complete.

I am going to check my hard disk drive to see if there aren't any third party problem.

    vincent@berlioz:~/photos2$ du -sh --exclude=.git/annex
    510M	.

Yet it shrank by 300 MB.
