* @endcode
* @attention Never invoke an asynchronous functor with arguments passed by
* reference with sigc::ref() (or at least not if you don't know exactly what
* you are doing)!
* @note You have to be careful that T_functor, arguments bound to it and
* passed arguments are threadsafe.
* Asynchronous tunnels copy T_functor and passed arguments on invokation of
* the tunnel functor and destroy them in the context of the server thread
* (the thread receiving the message which is different from the sender thread!).
* e.g. never do this:
* @code
* struct MyThread
* {
* void do_something(const GLib::RefPtr<X>& p) {}
* };
*
* Glib::RefPtr<X> p;
* open_tunnel(mythread, &MyThread::do_something)(p);
* @endcode
* For safety reasons you can apply this rule also for synchronous tunnels,
* although the invokation behaves differently: Still T_functor is copied but
* passed arguments are sent by reference to the server thread.
* The same rules apply for sigx::request_f
