I wrote my cleanup code like this :

def handler(req):
	# do something dirty
	# do another dirty thing
		# do usefull work
		# cleanup the mess

Can the finally block be interrupted by Apache ? Do I really need to
implement cleanups instead ?

Concerning the circular reference fix, I'm switching to the python-dev
mailing list.
