In the servlet 2.3 spec (supported by Tomcat 4.0), there are new
Application Event Listeners, and the events you can register listeners for
include "application startup" and "application shutdown". There is no
such portable mechanism in servlet 2.2 (supported by Tomcat 3.2).

For Tomcat 3.2, the only two circumstances where Tomcat actually calls the
destroy() method of a servlet are:
* Your context is being reloaded because of a changed class
* Tomcat is being shut down
But, as you noted, you cannot rely on this behavior portably.
