Yes, much simpler, and servers can come up with a good block size.

Here's the tail end of the CGI example.

    result = application(environ, start_response)
    try:
        if hasattr(result, 'read'):
            result = iter(lambda: result.read(BLOCKSIZE), '')
        for data in result:
            write(data)
    finally:
        if hasattr(result,'close'):
            result.close()
