  Shot noise is not normally evident in bulk solid-state conductors, since it
is strongly attenuated by inelastic collisions. The ``anomalous'' emergence of
macroscopic shot noise is discussed in G. Gomila and L. Reggiani, Phys. Rev. B
62, 8068 (2000). We remark on the consistency of this linear diffusive model at
the large voltages and currents needed to see the effect.
