Are your module-level variables mutable or immutable?  If they are 
mutable, then I would say you can't go with a threaded model here (but 
may be mistaken). 

You may be able to use isapi-wsgi with a custom application pool to 
achieve what you are looking for.  If you can restrict the application 
pool to only use one thread per process (which I am not sure how to do) 
and then use multiple processes (properties -> performance -> maximum 
number of worker processes), you may be able to achieve what you are 
trying to do.  You might want to ask more questions on the isapi-wsgi board.

Another project to look into is PyISASPIe which is a similar concept to 
isapi-wsgi.  The author of that project is active on the boards and 
might be able to suggest to you how to limit the application pool as 
described above.
