FWIW: I don't know if it changes anything, but when deploying Django projects on some clients who uses Windows as server, I'm using this piece of code to workarround this issue:

## Fixes "IOError: [Errno 9] Bad file descriptor" when in pythonw.exe of Windows

if sys.platform.find('win') != -1 and sys.executable.find('pythonw') != -1:

    blackhole = file(os.devnull, 'w')

    sys.stdout = sys.stderr = blackhole

##

Is not my intention to remove print statments neither to send they to a file. For this I'm using logging module.

I really expect they to be silently ignored, bothering not my user.
