* Jetty Handlers does not let jamon start/stop time them. It seems the request is done by the time jamon gets it.
* To overcome this use the jetty api to get the time of a request for a page. If it isn't a jetty request then call
* the parent. Note although start is called because the timing for jetty is done after the request is finished
* 'active' statistics will not be accurate.
