DataWriter in the below code work on MacOS but not Linux

# FIXME:
 # stdin=pipettor.DataWriter('\n'.join(names) + '\n')
 # for some reason work on MacOS, but not Linux
 transcript_beds = {}

 tmpNamesFile = fileOps.tmpFileGet()
 fileOps.writeLines(tmpNamesFile, names)
 with pipettor.Popen(['bigBedNamedItems', '-nameFile', bigbed, tmpNamesFile, '/dev/stdout'],
                     stdin=tmpNamesFile) as fh:
     for b in BedReader(fh):
         transcript_beds[b.name] = b
 os.unlink(tmpNamesFile)
