Hmm, I think you still have a race in the OnDestroy: if I understand flock() correctly, the lock is released as soon as you close the filehandle, so the unlink() happens after the lock has been released.

Hmm, I see what you mean. The thing is that the OnDestroy doesnt happen until after the record that this job is about is deleted from the DB. So once the deletion occurs the lockfile is more or less irrelevent as no other job can now get it. We requery the queue after every successful task, so I _think_ the race condition is covered. But maybe im wrong, and maybe there is even a better way to go about this.

Actually the more i think about it the more I think I am wrong. Hmm.
