There exist a script contrib/workdir/git-new-workdir,
which creates a new working copy that literally shares the same object store.
It will share both object store and branches, so some care must be taken:
branch which checkout out in one shared working directory must never be updated
(committed or pulled into) from the other shared working directory.

Said that, I personally find this trick very useful for browsing alternate
branch code and quick bug fixing.
