sigc++ "signals" have nothing, absolutely *nothing* to do with POSIX
signals. sigc++ "signals" are just a list of callback functions, wrapped
up in all the typesafe goodness that C++ can provide.

the connection remains in place until either one of the two objects (the
signal owner and the "connected object") is destroyed, or the code
explicitly disconnects it.
