figured out myself :blush: :blush:

def demo_app(environ,start_response):
    from StringIO import StringIO
    stdout = StringIO()
    print >>stdout, "Hello world!"
    print >>stdout
    h = environ.items(); h.sort()
    for k,v in h:
        print >>stdout, k,'=',`v`
    k=start_response("200 OK", [('Content-Type','text/plain')])
    for x in range(1, 100):
        k(str(x))
        time.sleep(1)
    return [stdout.getvalue()]

This function-programming style is very odd :-) ................and
PEP 333 document is so hard for a newbie
