Stopping a Distributed Ruby Service -

I have a script that produces a handler object and waits through DRb.thread First, join a DRb service . I would prefer the script running until I was killed clearly, so I put

  trap "INT" in the DRB.stop_ervice and   
 which Successfully closes the DRB service and Ruby goes down to 1.8, but seems to have a stalemate below 1.9 (on OS X 10.6.7). By sampling the process, some strings of spinning are shown in  semaphore_wait_signal_trap .  
 I think the way I am calling  stop_service , I'm doing something wrong, but I'm not sure what happened. Can anyone give me some signs about it correctly?   
 
 
 OK, I think I have found solutions If I replace the original code with  
 , start the DRB.read. Ensure rescue interrupts that the DRb.stop_service end   
 Ctrl-C works and stops the service.
