should we really have a thread pool per HTTP client? seems like this is intended to be a singleton. Also, it implements: http://download.eclipse.org/jetty/7.6.14.v20131031/apidocs/org/eclipse/jetty/util/component/AbstractLifeCycle.html

Which implies to me that it should be stopped when we're done using it (for that matter, we should probably also be sending it a start?)

Am I missing something here?
