This behavior is defined by the WSGI specification.  If you don't want this
behavior, you don't want WSGI.

Perhaps you want to write a native Twisted application, perhaps using
klein.  Or you could find one of the WSGI variations that aims to support
asynchronous operation instead of multithreaded operation (but Twisted
doesn't provide a container for any of those).
