- cron's granularity is in minutes, it would be a little silly for
cron to wake up every second and cron is not really designed for such
frequent runs.
- Just write a loop-forever script and 'sleep 1' at the bottom of the
while [ true ]; do
sleep 1
if [ -z "`ps ax | grep <proc> | grep -v grep`"]; then
#start daemon
