* The 'touch' command.

* This is useful for jobs that potentially take a long time, but you still want
* the benefits of a TTR pulling a job away from an unresponsive worker. A worker
* may periodically tell the server that it's still alive and processing a job
* (e.g. it may do this on DEADLINE_SOON).
