run-one-constantly waiting for previous instances to end

[Stephen Rees-Carter]

I'm trying to use run-one-constantly within a crontab to ensure a "daemon script" is always running. However, it seems that run-one-constantly doesn't stop quietly like run-one when it's already running, it just keeps runing without doing anything until the previous command finishes. If this is triggered by a frequent cron, you'd end up with a lot of processes doing nothing.

See the attached screenshot, all of the commands at the bottom are 'running' - but only one is being processed. You can see all of them in the ps aux at the top.

Let me know if you need any debug information.
