And since by now we've strayed far from "just reuse the newline", we
might as well parse all notifications and react only to READY=1, it's no
big difference anymore:

| timeout 1234 socat \
|     "unix-recvfrom:$NOTIFY_SOCKET,unlink-early,fork" \
|     'shell:if grep -x READY=1 >&3 ; then kill $SOCAT_PPID ; fi' \
|     &
