;;; ;;; However, that doesn't explain our OS X problem.  I added some debug           
;;; ;;; printouts, and can now report positively that (a) the fork() call             
;;; ;;; returns normally in the parent process, providing an apparently-correct       
;;; ;;; child PID value; but (b) the fork never returns in the child.  It             
;;; ;;; doesn't ever get as far as trying to enable SIGTERM.                          
;;; &                                                                                 
;;; ;;; Is it possible that something in the child's fork() processing will wait      
;;; ;;; around for a response from a service that's already died?  Why is fork()      
;;; ;;; dependent on any outside service whatever --- isn't that a certain            
;;; ;;; recipe for system failures?                                                   
;;;                                                                                   
;;; I asked Apple this issue. This is a bug of Mac OS X. The problem is registered    
;;; to their bug database for the appropriate eingineers for investigation.           

This problem is fixed for Mac OS X 10.2.
