/** Destroy needs to clean up the context completely.
 * 
 * The problem is that undoing all the config in start() and restoring 
 * a 'fresh' state is impossible. After stop()/destroy()/init()/start()
 * we should have the same state as if a fresh start was done - i.e
 * read modified web.xml, etc. This can only be done by completely 
 * removing the context object and remapping a new one, or by cleaning
 * up everything.
 * 
 * XXX Should this be done in stop() ?
