i didn't notice that within the loops. sorry if it was there. i don't
have it anymore to check.

I would do this:

gint
my_100msec_handler()

{
	static int direction = 1;
	static int i = 0;

	if ((i += direction) == 100) {
	    direction = -1;
        } else if (i == 0) {
	    direction = 1;
        }

	gtk_progress_bar_update (i);
	return *running;
}

this will modify the progress bar every 100msecs, which i would
imagine is fast enough.
