I should point out that this issue with sessions if applicable, isn't actually restricted to a multithreaded server. Technically it could occur with a multiprocess server as well, it just may be easier to trigger a problem when a multithreaded server is used. This issue with sessions previously came up in: http://groups.google.com/group/django-users/browse_frm/thread/a7d42475b66530bd I don't know if there was any subsequent work on Django to look at how big a problem if any this is. Anyway, what was important in what I was saying was not so much the session issue, but that you should just test your system thoroughly to make sure there aren't any problems in general if using a multithreaded server.
