-----------------------------------+----------------------------------------
 This proposal suggests adding to asio the ability to invoke a handler
 whenever a unix signal arrives.

 Motivation:

 1. The extension lets the user have a unix signal handler of an arbitrary
 signature.

 2. The extension also removes the "async-signal safe calls" restriction
 from a handler of a unix signal.

 The extension is supposed to be used like this:

 void on_signal(boost::system::error_code const& error)
 {
     if (!error)
         cout << "sigint received" << endl;
 }

 int main(int argc, char const* argv[])

 {
     boost::asio::io_service ios;
     boost::asio::posix::signal_handler<SIGINT> sigint(ios);
     while (true)
     {
         ios.reset();
         sigint.async_wait(boost::bind(on_signal, _1));
         ios.poll();
     }
 }
