multiple checked out branches

[Domenico Andreoli <cavokz@gmail.com>]

Hi again,

  I would like to contemporaneously work with multiple branches out of
the same git repository. This does not work out of the box.

So I prepare multiple copies of the same repository, every one will have
its own checked out branch but I want to share most of their .git subdir.

I surely want to share the object db, the local and remote refs.
This way it is enough to make a round of fetches/merges/pushes to have
all the shared-repositories up to date.

I expect to do the trick with some symlinks but I am not an expert of
git internals. Which traps are waiting me? Any hint? Thank you.

Regards,
Domenico
