Seems to work much, much better even inside a function, and even
inside dash if i add the trap
trap 'echo "Started job reaper successfully"' USR1
inside, and instead of JOBREAPER=$!
i=${!}
sleep 1
if kill -USR1 ${i} >/dev/null 2>&1; then
JOBREAPER=${i}
else
printf "%s!! Incapable shell, cannot start zombie child reaper%s\n" \
"${COLOR_ERR_ON}" "${COLOR_ERR_OFF}"
fi
But understand i do not.
