Of course this works for the synchronous server where there is an explicit loop;
an asynchronous server needs to call { service->stop(); }  My experiment shows
that it is does not produce any visible failure under SuSE; however, it is not
clear whether io_service::stop can be called from within a signal handler. 

Help?
