I don't know if this is the "correct" way to do it, but I found I had to put

while (gtk_events_pending()) {
    gtk_main_iteration()
}

right after the call to set_fraction() to get the progressbar to update.  This
was is a tight loop where I'm loading values into a ListStore.  I never
could get it to work with timeouts.  Looking at the docs, I see that there's
also gtk_main_iteration_do(), which may be better for this.
