Of course there is nothing special about COMM_WORLD, and there is no way
to get consistent naming of serial objects.  This would only ensure that
all processes in a communicator have the same name for parallel objects
and that no process on that communicator uses the name for a different
object.  There is no guarantee that this name is never used for an
object on a different communicator.
