g_io_add_watch() allows you to watch the status of certain fd's. Here is
some documentation:
http://developer.gnome.org/doc/API/glib/glib-io-channels.html
(looks to me like the underlying mechanism for gdk_input_add())
Now if Orbix/ORBACUS is able to tell which socket they're using to listen
to incoming requests, you could set a watch on that socket. So if you add
a watch on the condition G_IO_IN, your function will be called as soon as
there is incoming data available. In your function you just process a
couple of steps of the Orbix/ORBACUS event loop.
