Actually, the solution for Arch-over-sftp should also work for bzr.  Of

The abstraction it would interact with is the lockable files that are
associated with that copy of the branch and repository data.

Personally, I would reimplement umasks on top of AtomicFiles, and
specify the umask in BzrBranch.controlfile.
