I have found that when gtk gets rapid updates to a view it usually stays
blank until it gets a chance to redraw the screen.  You could put a
counter in place before you do the callback and pause it from time to
time so the screen can re-draw.  Horky I know.  We also found that
updating a lot of data to a treeview model goes a lot faster if you
switch the treemodel out for a blank one while you add info to the real
one, then switch it back when finished.

Personally I have never had any luck in trying to run the 

while gtk.events_pending()
	gtk.mainiteration()
# or something like that

It always locks up and I have to kill the app externally.
