@raykrueger Help me out here - do the following lines in resque-lock accomplish the same goal?

https://github.com/defunkt/resque-lock/blob/22f276b5e1cd322865d8db95d5c8834d40b7fac2/lib/resque/plugins/lock.rb#L58-62

Or is the on_failure_lock added for the purpose of sending exceptions like this one into the locksmith failure backend specifically?
