-- Enters loop which polls gps device. Reads gps data into gpsd structure.
-- On success, emits a signal which is captured by GpsWindow. In turn, GpsWindow
-- displays the data.
--
-- Is aborted when Thread class receives the appropriate disconnect signal
-- from GpsWindow, either on program close or via the user clicking
-- disconnect.
