Hi Steve,

When I came to write a blog post about the various cron wrappers I've written that use lockrun as their locking mechanism I realise that I've never thanked you for it.

It's the most elegant job locking solution I've found and I've snuck it into more systems than I can remember!

Overdue thanks for sharing this, it's great.

Regards, jon.
