I first hear about asio signals, but I believe purpose of these signal  
facility in asio is only to help you to implement *waiting* for signals,  
like SIGCHLD, or SIGUSR{12}, whateverer you may choose for your IPC  
communication. You should not misuse asio for general signal handling.  
Normally signals are instantaneous things to be delivered right now right  
here without any regard in which state the target is.
