-> Is there reason to believe that quixote applications will work reliably -> under this multi-threaded server? I wouldn't expect this to work -> reliably -> without at least hacking Quixote's Publisher.__init__ and -> get_publisher() -> to maintain a separate publisher for each thread. You are correct, suh. This is a bit of dilemma. Quixote apps aren't thread-safe out of the box, http://issola.caltech.edu/~t/q2-doc/multi-threaded.html so I guess WSGIUtils isn't a good default server for Quixote ;(. I'm not sure what is, though. Note the PEP comment, http://www.python.org/peps/pep-0333.html#thread-support so maybe WSGIUtils should be changed to allow this? QWIP should also (by default) complain about being put in a multi-threaded environment; env['wsgi.multithread'] is probably the right way to check this. --titus
