                                WorkerHasTask

HTTP handler for workers ensuring that a job still exists.

This handler helps eliminate certain race conditions in NPSGD. Before a worker sends an e-mail with job results, it checks back with the queue to make sure that the job hasn't already been handler by another worker (this could happen if the queue declares that the first worker had timed out). If there is no task with that id still in the processing list then an e-mail being sent out would be a duplicate.
