      This function's behavior changed in 4.0.3. The temporary file is also
      created to avoid a race condition where the file might appear in the
      filesystem between the time the string was generated and before the
      the script gets around to creating the file. Note, that you need
      to remove the file in case you need it no more, it is not done
      automatically.
