behaviour different for command line option --stop between pt-kill and pt-heartbeat?

[Alexander Hollerith]

Hi, 

it seems that pt-kill and pt-heartbeat behave differently in regards to the --stop and --sentinel options.

I can easily put something like this into a cron for pt-heartbeat to restart it regularly:

30 * * * * root /usr/bin/pt-heartbeat --utc --update --interval 1 --host XXX --database percona --table heartbeat --stop --sentinel /tmp/pt-heartbeat-hourly>/dev/null

I couldn't find a comparably convenient way to achieve the same for pt-kill.

Thanks

Alex
