(** [save_as filename ?mode f] is similar to
    [Control.with_open_file_bin] except that writing is done to a
    temporary file that will be renamed to [filename] after [f] has
    succesfully terminated. Therefore this guarantee that either
    [filename] will not be modified or will contain whatever [f] was
    writing to it as a side-effect.
