 WaveMoL's IDWaveMoL thorn only sets up ID on the current timelevel.
 However the gaussian.par test using radiative boundary conditions which
 require valid values on the previous timelevel. With PUGH it seems that
 these values are usually zero (either because PUGH clears memory or
 because malloc() does). With Carpet however, poisoning is the default and
 one finds that NaNs show up from the boundary, one per timestep.

 This can be avoided by setting mol::initial_data_is_crap = yes (or the
 equivalent Carpet parameter if one uses Carpet) in the parfile.
