This is definitely a good move, since it moves node creation and
deletion to the containing node instead of the File.  A coherent move in
the same direction would be to change Group._f_rename(newname), which
changes a group's own name, to Group._f_rename(oldname, newname), which
would change a *child's* name.  The name of a node should only matter to
the containing group.  Also, Leaf._f_rename would go away.  So,

  >>> group.oldname._f_rename('newname')
would change to:
  >>> group._f_rename('oldname', 'newname')

which is more coherent with the way file systems work.
