subapplications can not work with spawn-fcgi?

[vlion]

code.py:
import index
urls = (
  "/", index.index,
)
app = web.application(urls, globals())
if __name__ == "__main__":
    web.wsgi.runwsgi = lambda func, addr = None: web.wsgi.runfcgi(func, addr)
    app.run()
use python code.py is ok!
but use spawn-fcgi can not work!
