Whether or not "RESPONSE" is "None" should not be dependent on
the "Data.fs" ("RESPONSE" is recreated for each request and
is independent of persistent objects).

"REQUEST.RESPONSE" is set up in
"ZServer.HTTPServer.zhttp_handler.continue_request".
It should be impossible that is is "None".


Maybe, we have a memory corruption.
I have seen objects magically becoming "None" in
Python versions with memory corruption problems (Python 2.1.1).
