[mod_python] mod_python and threading.Thread doesn't start

I have been developing an idea of what is wrong. Can you now try this 
slightly
different variation on the code and post back the result. Am interested 
in the
id of "__builtins__" and whether it is the same as 
"__builtin__.__dict__". On
my system they are actually the same object. Note this problem was 
possibly
only introduced with 2.3.5 and 2.4.

import threading
import time
from mod_python import apache

import __builtin__

def openfiletest(req):
     req.write(" builtins=%d "%id(__builtins__))
     req.write(" builtin=%d "%id(__builtin__.__dict__))
     try:
         a = file("/tmp/test", "w")
         req.write("file() was OK\n")
     except Exception, e:
         req.write("file() threw exception: " + str(e) + "\n")

def handler(req):
     req.write("In main thread: ")
     openfiletest(req)
     req.write("In child thread: ")
     t = threading.Thread(target=openfiletest, args=(req,) )
     t.start()
     time.sleep(1)
     return apache.OK
