            Description

            It appears we have interleaved synchronization that is causing a deadlock. It is triggered during session invalidation. In this case, something in Seam is invalidating the session and that invalidate call makes it's way down until we try to shutdown our SessionDispatcher.Monitor. At that point it grabs a lock on the collection of "contexts" in order to iterate through and clean up stuff. During this process, though, it needs to grap a lock on the SessionMonitors collection. Unfortunately, a thread already has the lock but then needs the lock on the "contexts" collection as well.
