Just being inside a call to gtk_main isn't enough - the main loop
actually has to be running. What the above snippet does is run
all pending events and high priority idle functions, then return
immediately. (The drawing is done in a high priority idle)

[ Maybe gtk_progress_bar_update should redraw itself instantly instead
  of queuing a draw? ]
