And you can post update messages from the thread using a queue of some
kind.  The GUI just has to have a timeout that checks the queue and
updates the gui with messages (percent complete, bytes transferred,
etc). Or have the thread use gobject.idle_add to schedule a callback in
the main thread that will check on the upload status and update the GUI.
