You will find that several new things in Servlet 2.3 actually increase the
dependency on the container's notion of a Context -- for example, application event
listeners. This can be done in many ways, of course, but at some level a completely
"stand alone" session implementation is an ideal, not a practical reality.

Is 3.3 ready to give up on JDK 1.1 compatibility? If not, the extra effort to
maintain it is not particularly "productive" from a Tomcat 4 point of view.
