4909	WSGIHandler is not threadsafe	colin@…	Jacob	"The __call__ method of WSGIHandler is called from multiple threads, however there code that checks for the middleware being setup is not thread safe.

{{{if self._request_middleware is None:
            self.load_middleware()}}}

Multiple threads can launch into load_middleware at once, leading to corrupt lists.

The attached patch uses a lock to protect the middleware loading if it's required."		closed	Uncategorized	dev		fixed			Ready for checkin	1	0	0	0	0	0
