If your doing lengthly calculations... they should be split up into
short itterations, each itteration runs in a GSource... if you use a
timeout for this GSource, then you can play with your apps responsivness
by playing with the interval.

If you need your application to refuse button & key press events
(but still refresh itself graphicly), you should set the sensitivity
of your buttons during the lengthly operation (and just ignore key
press events).
