code: public static <T> void poll(String name, String description,
  			MonitorableRegistry registry, int updateInterval, Supplier<T> poller,
  			ValueSemantics semantics, Unit<?> unit) {
  		new PollingMonitoredValue<T>(name, description, registry,
  				updateInterval, poller, semantics, unit);
  	}
docs: Convenient factory method to create pollers you don't care about keeping
  – that is, pollers which should be registered and start updating their
  value, but which you don't need to hold a reference to (because you will
  presumably just be modifying the polled source).
