The tree view listens to the model's signals so that it can update  
immediately.  However, the drawing is deferred with an idle, to avoid  
doing lots and lots of updates synchronously.  That means that the  
updates don't actually show up on the screen until you return control  
to the main loop.  (It can be as simple has "Gtk2->main_iteration  
while Gtk2->events_pending;"  every so many rows.

Another trick for speeding up treeview updates is to unhook the model  
from the view, add the rows, then reconnect the model to the view.   
This avoids all of the update callbacks for each row add, and simply  
does one update when you reconnect.  I doubt that accounts for 2  
minutes of activity, but it's worth a try.
