As far as I know,
stdout is usually buffered (not necessary) in both C++ and Python
stderr is non-buffered in both C++ and Python (I can't imagine the point of
stderr if it were buffered)
Even with this, stdout usually come immediately - the situation you have
shouldn't happen.
Are you using an IDE? If so, which one?
