  PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
  of strict) error handler to escape surrogates

  handle_system_exit() flushs files to warranty the output order

  PyObject_Print() writes into the C object stderr, whereas PySys_WriteStderr()

  call sys.stderr.flush() and fflush(stderr).

  Fix refleak in internal_print() introduced by myself in r81251

  _PyUnicode_AsDefaultEncodedString() uses a magical PyUnicode attribute to
  automatically destroy PyUnicode_EncodeUTF8() result when the unicode string is
  destroyed.
