It doesn't have any impact on the REST interface right now, but it did cross my mind that
it might help with the out-of-memory errors you reported.

MessageServlet (REST servlet) only removes old WebClient instances if they explicitly unsubscribe.
 A WebClient instance for a browser who just ceases to collect messages (which seems pretty
typical for web applications) will never be cleaned up as far as I can see.

The cleanup logic I implemented for AjaxWebClient could possibly be moved into the main WebClient
class.  If that were done, the Timer task would be easy to add to MessageServlet.
