// Glib::IOChannel reference counting issues:
//
// Normally, you'd expect that the C++ object stays around as long as the
// C instance does.  Also Glib::wrap() usually returns always the same C++
// wrapper object for a single C instance.
//
// Unfortunately it isn't possible to implement these features if we didn't
// create the underlying GIOChannel.  That is, when wrapping existing
// GIOChannel instances such as returned by e.g. g_io_channel_unix_new() or
// g_io_channel_new_file().  Neither is there a way to hook up a wrapper
// object in an existing GIOChannel, nor exists any destroy notification.
//
// So that means:  If the IOChannel is implemented in C++ -- that is, our
// GlibmmIOChannel backend is used -- we use the GIOChannel reference
// counting mechanism.  If the IOChannel backend is unknown, then the
// wrapper instance holds always exactly one reference to the GIOChannel.
// The wrapper object itself is then managed via our own refcounting
// mechanism.  To do that a utility class ForeignIOChannel is introduced to
// override reference() and unreference().
