[Pythonmac-SIG] print to console window very slow

[Christer Fernstrom]

Actually, printing from the application is fine. It's the traceback that's
really slow (watching it feels like watching an old movie where a policeman
takes down a report on a typewriter with two fingers). Environment: Python
2.1, carbon, MacOs 8.5.1 (French). Since traceback writes to sys.stderr,
then maybe it's sys.stderr that's unbuffered? And maybe for good reasons?
