+What steps will reproduce the problem?
+
+1. Create a fresh git-annex repository
+2. Add a directory tree to it with about 300,000 files in it
+3. wait
+4. change the tree; attempt a git commit
+
+What is the expected output? What do you see instead?
+
+git commit hangs due to the large number of loose objects created during the git annex add. If git annex had stopped to repack the git repo a few times along the way, I think this might have been avoided.
+
+What version of git-annex are you using? On what operating system?

+git-annex version: 4.20130323
+local repository version: 3
+default repository version: 3
