Made a fix to the xml saving.

                waveform_row = waveform._row(sim)

                waveform_row.process_id = procrow.process_id

            except:

                waveform_row = waveform

                row = sim.RowType()

                for a in lsctables.SimBurstTable.validcolumns.keys():

                    setattr(row, a, self.params[a])

                waveform.waveform = self.waveform

                # Fill in the time

                row.set_time_geocent(GPS(float(waveform.time)))

                # Get the sky locations

                row.ra, row.dec, row.psi = waveform.ra, waveform.dec, waveform.psi

                row.simulation_id = waveform.simulation_id

                row.waveform_number = random.randint(0,int(2**32)-1)

                ### !! This needs to be updated.

                row.process_id = "process:process_id:0" #procrow.process_id

                waveform_row = row

            sim.append(waveform_row)

            #del waveform_row
