  In their Rejoinder [arXiv:1105.1316v1], Levin and Pakter repeat some of the
points raised in their previous Comment [arXiv:1104.0697v1] (already refuted in
our first Reply [arXiv:1104.5036v1]), and present some new ones concerning our
recent publication [arXiv:1008.1421]. Their new criticisms are also refuted in
the present Surrejoinder, whenever relevant for the results of our Letter. It
is our understanding that, in their Comment and Rejoinder, Levin and Pakter do
not provide any relevant contributions to the problem addressed in our previous
work. We therefore consider the present discussion as closed.
