This sounds good to me, too. (Though I think SIGINT by PID might be
good, I see no need for SIGTERM by XID).

But are you saying it *is* safe with SIGTERM to a backend? I always
thought it was before, but after what you said earlier in this thread, I
changed my mind... (Unfort, I'm not well enough into the deep ends of
the code to say which is right...)
