What I have noticed is that the ContinuationBayeux.destroy() method is not
getting invoked when the webapp is reloaded. This results in threads that
remain open even after the webapp is reloaded. I'm currently using
Jetty-6.1.14. Since ContinuationCometdServlet creates the new
ContinuationBayeux object, it should also destroy it when the servlet is
destroyed. Can this be fixed?
