  Bromberg and Ulcigrai constructed piecewise smooth functions f on the torus
such that the set of angles alpha for which the Birkhoff sums of f with respect
to the irrational translation by alpha satisfies a temporal distributional
limit theorem along the orbit of a.e. x has Hausdorff dimension one. We show
that the Lebesgue measure of this set of angles is equal to zero.
