> I am rewriting my software to use the new API that comes with 4.2-alpha2. Returning a Cancellable from HttpAsyncRequestHandler#handle() seems like a good idea for long running requests like long polling. But I don't ever see Cancellable#cancel() being called.
> I telnet into my server and type the necessary HTTP to start a long running request. A Cancellable is created and returned from handle(). Then I kill the telnet process, thereby killing the connection. I expect cancel() to be invoked in the connection's Cancellable at this point, but nothing happens. cancel() is not invoked in my Cancellable, and there are no calls to HttpAsyncServiceHandler#closed(), HttpAsyncServiceHandler#exception() or DefaultServerIODispatch#onClosed() either.
