      57   * Signatures)), but also seems generally reasonable. #GDBusMessage wraps its

      60   * The limit is actually set to be a lot greater than 64, to allow much greater
      61   * nesting of values off D-Bus. It cannot be set over around 80000, or the risk
      62   * of overflowing the stack when parsing type strings becomes too great.
      63   *
      64   * Aside from those constraints, the choice of this value is arbitrary. The
      65   * only restrictions on it from the API are that it has to be greater than 64
      66   * (due to D-Bus).
