I am on a direct remote. I just deleted a directory, and would like to commit that change.
After I run git annex sync I see a line which says commit, and that is all. I tried to wait it out a few hours, but nothing. Why does git annex hang?
Here is the output of strace git annex sync:

Sorry didn't get to this until now.
It would probably help to pass the --debug option to git-annex sync, and paste the output up to the point where it hangs.
