This is not totally correct. Application callbacks can only cause GTK+
to *invalidate* regions. In sane code, redrawing *never* happens in a
user callback but only in expose event callbacks, which are triggered by
GTK+ *only* when the time for redrawing comes.

Nevertheless, there are still issues with GTK+ and synchronization of
events. See [1] and [2] for a good explanation of these.
