>       SYNOPSIS:
> 
> When running Notify_Service with asynchronous dispatching (as 
> enabled in 
> the svc.conf file in TAO/orbsvcs/Notify_Service) Ctrl-C will hang, if 
> there is still a consumer registered at the service.
> 
>       SAMPLE FIX/WORKAROUND:
> 
> The root problem is, that the Notify_Service_Driver::run() blocks on 
> worker_thr_mgr()->wait(). Notify_Service_Driver::shutdown() calls 
> orb_->shutdown(), but does not cancel the dispatching threads, which 
> seem to be managed under the same thread manager.
> 
> Consumers can not disconnect after Ctrl-C anymore either, as the orb 
> event loop is already down.
> 
> Workaround: Initializing -ORBRunThreads 0 causes ::run() to end up in 
> orb_->run() instead of ...->wait(). This at least works for 
> the "single 
> threaded orb" configuration.
