Perhaps it was a misunderstanding -- signals sent to the parent will hit the
child process, but not the other way around. (If it did, kill %1 in your shell
would kill your shell as well.)

How about SIGINT, and failing which, notifying the user that the program refuses
to stop, and allowing for SIGTERM or SIGKILL?
