Are you writing this as a CGI process in Apache/Win32?  Have you 
redefined your stdout to be binary?  By default, Python opens its stdout 
as binary, so when you write this out to the socket, the file system 
will "helpfully" translate 0A to 0D/0A.  You need something like this:

    import msvcrt
    msvcrt.setmode( 0, os.O_BINARY )
    msvcrt.setmode( 1, os.O_BINARY )
