Mmh. I wouldn't be surprised if under pythonwin, sys.stdout is not the true
python sys.stdout. Check the following:
sys.stdout is sys.__stdout__
The answer is probably false. In that case, they may have implemented some
incomplete object whose flush method is broken, or something similar. I can't
confirm, as I don't have windows access, so this is just a guess.
