Well, this is a severe limitation on the applet-widget part.  Here's how to
"fake it"

What happens is that, applet_widget_init just initializes gnome with corba
and disables the session managment (because for applets that's taken care of
by the panel).  There's one last tidbit it does, which is to set an internal
flag to call gtk_main_quit when the last applet dies.  SO, to fake it,
just do gnome_CORBA_init_with_popt_table, then in case we're an applet,
gnome_client_disable_master_connection, and then bind to the destroy signal
on the applet widget and call gtk_main_quit.

Hmm... seems hacky?  It is.  All this will be improved in gnome 2.0.

Another option.  Build another binary.  One binary will do an applet,
one binary will do a normal app.  Most of the code can be shared.
