  3 + * When parsing files, while reading an object, if there are too
  4 + many consecutive errors without enough intervening successes, give
  5 + up on the specific object. This reduces cases in which very badly
  6 + damaged files send qpdf into a tail spin reading one character at
  7 + a time and reporting warnings.
