 // Work does a single unit of work: tries to take out a WorkItem from the queue, ssh-es into a given machine,
 // gathers data, writes it to the shared <data> map, and creates a gorouting which reinserts work item into
 // the queue with a <pollingPeriod> delay. Returns false if worker should exit.
