Well, 
you either need another scheduled function (prolly g_idle_add) or start
a separate thread when entering your callback and join it before ending.

You prolly want to avoid multi-threading for such a rather limited
use-case. 

Also, I've noted a flaw in my pseudo-code around setting dialog to NULL
which does not change the pointer that has already been passed to
update_pbar ... a static global would prolly do here or smth. similar.

HTH,

Karl.
