+Subject: [PATCH] Avoid creation of zombie process by load_config
+
+Previously, a zombie process was created when the process forked in
+load_config terminates because the parent does not call wait or waitpid.
+It is unreasonable to wait for the child because a user may exec their
+autostart script into a long-running process. Instead, the parent now
+simply ignores SIGCHLD which allows the child to be reaped immediately
+upon termination.
