+Note that this really belongs in a unit test that builds the library
+since it depends on a change to the library.
+
+For this to work accurately a check in QSensorBackend::newReadingAvailable()
+needs to be commented out while building the library. The check is:
+
+    if (d->updatePolicy == QSensor::PolledUpdates)
+        return; // We don't emit the signal if we're polling
+
+With this check in place, the use of sensor.poll() to measure performance
+does not work.
