Receiving app launch notification in command line tool

Hi,

is it possible to have a Cocoa command line tool launch an application
and be notified once the app is up and running?
It seems straightforward, but my tool never receives the notification.

Thanks,
-Ralph.

// problem: launchNotification: never gets called

       name: NSWorkspaceDidLaunchApplicationNotification
       object: nil];

       NSLog(@"app could not be launched");
   }
   else{
       NSLog(@"app was launched, now waiting for
NSWorkspaceDidLaunchApplicationNotification");
       [[NSRunLoop currentRunLoop] run];
   }

   [pool release];
   return 0;
