this doesn't cause never ending recursion if MY_VALUE is a single
value. gtk_spin_button_set_value (foo, val) does nothing if "val" is
equal to the current value.
this is a classic problem for Model-View-Controller programming, and
blocking the signal is not normally the right way to deal with it.
how do you compute MY_VALUE?
