[Moin-user] iis + isapi_wsgi + moin, circular reference?

I envision my skeleton being added to others littered around here ;)

Did that, and at first got a encode error from line 510 of init.py,
changed it to:
            self.path_info = path.encode("utf_8")

(based on http://docs.python.org/library/codecs.html - utf_8 encoding
exists but no utf-8 even though it is mentioned everywhere - don't ask
me to understand)

Very strangely, I now cannot reproduce this error. 
I tried iisreset, even rebooting and now I only get this traceback:

I've turned on all the debugging stuff I can find,

------------------
from wsgilogfile:
 [DEFAULT]
logfile=moinwsgi.log

# Default loglevel, to adjust verbosity: DEBUG, INFO, WARNING, ERROR,
CRITICAL
#loglevel=INFO
loglevel=DEBUG
------------------

but only ever get this in the logs:
2008-12-15 13:33:39,869 MoinMoin.log INFO using logging configuration
read from "e:\moin\wikis\add\wsgilogfile"

Any ideas?
I thought some base objects init method was not being called, but that
does not seem to be the case.
I thought that perhaps iis is multithreaded and there is some threading
issue. Am back to this one actually, since I can't find the base code
that I thought set multithreading, runonce, etc to false when it's a
wsgi app...
