The io_service can't exit the run command until all the work is 
complete.  You need to put the io_service.run() into its own thread if 
you want to still execute things in main.

boost::thread runningService(boost::bind(&boost::asio::io_service::run, 
io_service));
printf("Writting a line 1 \n");
sleep(5);
printf("Writting a line 2 \n");
runningService.join();

This will allow you to continue and execute code in your main function.  
The problem you'll run into is trying to close the thread properly.  I 
used the HTTP Server 2 example to create a class that ran my process but 
responded to an outside event to signal the class to stop processing.
