[Cppcms-users] Booster::aio's behavior

[CN <cn...@fa...>]

The following program does not terminate until 10 seconds has passed.
I want to terminate it immediately once I type "kill -SIGTERM". Is that
possible? How do I achieve that?
-------
class MyClass
{
private:
	booster::aio::io_service &io_service;
	booster::aio::deadline_timer timer;
public:
	MyClass(booster::aio::io_service &io_service)
		: io_service(io_service),timer(io_service){}
	void start()
	{
		io_service.set_timer_event(booster::ptime::now(),boost::bind(&MyClass::work,this,_1));
		io_service.run();
	}
	void work(booster::system::error_code const &e)
	{
		if(e)
			return;
		//do_my_job(); Do periodic job here.
		timer.expires_from_now(booster::ptime::seconds(10);
		timer.async_wait(boost::bind(&MyClass::work,this,_1));
	}
	void stop()
	{
		io_service.stop();
	}
};

cppcms::service *service;
void signal_handler(int signal_number)
{
	service->shutdown();
}

int main(int argc,char **argv)
{
	//init_signal_trap(); Initialize signal trap here.
	while(true){
		service=new cppcms::service(argc,argv);
		service->applications_pool().mount(cppcms::applications_factory<my_app>(),cppcms::mount_point(".*",1));
		booster::shared_ptr<MyClass> mc(new
		MyClass(service->get_io_service()));
		booster::thread t(boost::bind(&MyClass::start,mc));
		service->run();
		//Type "kill -SIGTERM" in OS so that signal_handler()
		gets called here.
		mc->stop();
		t.join();
		//Program does not reach here until 10 seconds passes!
		if(caught_signal > 0){
			switch (caught_signal){
				case 1: //SIGHUP
				case 14:{ //SIGALRM
					//Restart application.
					caught_signal=0;
					break;
				}
				default:{
					//Terminate program.
					//case 2: //SIGINT
					//case 15: //SIGTERM
					//caught_signal=0;
					return 0;
				}
			} //switch
		} //if
	} //while
}
