You don't need Gio.Application, but you do need a mainloop (and
Gio.Application provides one).
So alternatively you can do:
const Mainloop = imports.mainloop;
function main() {
[ code to setup dbus and start the async call ]
Mainloop.run('tag');
return 0;
}
main();
And inside the async call, when you want to exit the script, you would
do "Mainloop.quit('tag')"
