This is already the handling code for a fatal error, it's just trying to
tell the parent process that it went wrong. Completing the context:

            fprintf(stderr, "Could not acquire pid file: %s\n",
strerror(errno));
        exit(1);
    }

So there is already an exit(1), this patch doesn't change anything.
