With my limited experience with mercurial repo internals, dirstate and cache
probably belong to share's private data as well as bookmarks depending on the
I'm fiddling with approach where repo.vfs is pointing to shared location to
see if it could be changed.
The side effect could be that extensions that work with shared repositories would
most likely break with such change.
