 The tags can be used to push by parts to GitHub, which does not accept 1M at once:
 
-    remote='git@github.com:cirosantilli/test-many-commits-1m.git'
-    for i in `seq 10 10 100`; do
-        git --git-dir=tmp/repo.tmp/.git push -f "$remote" "$i:master"
-    done
-    # TODO for some reason I needed this afterwards.
-    git --git-dir=tmp/repo.tmp/.git push "$remote" 'master'
