I don't know if this would fly or not but...
Rather than conventionally returning NSTerminateLater you could try, assuming
your async driver calls are run loop sources, run the run loop as required
within - applicationShouldTerminate.
This should allow you the opportunity to get a window on screen (though not
necessarily using NSRunAlertPanel), process the user response, await the async
callbacks and exit when your cleanup is done.
