;;; 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.
