In order to send or receive binary files from Python CGIs under IIS 
(and Xitami) under Win32, I had to do the following in the scripts,
instead of using the -u option:

try:
    import msvcrt
    msvcrt.setmode(sys.stdin.fileno(), os.O_BINARY)
    msvcrt.setmode(sys.stdout.fileno(),os.O_BINARY)    
except:
    pass

The -u option broke something in cgi.py, I don't remember what.
