It could be different if the stderr object - i.e., PySys_GetObject("stderr") -
is actually not sys.stderr.  I don't understand why, but am not familiar
with PySys_*, so I offer that as a hypothesis you might be able to test.
By the way, since as you observed it's only calling fflush(), I think you
could leave Python out of it altogether and do this with just
   fflush(stdout);
   fflush(stderr);
