on the GtkTreeView tutorial (see below).  It was added early on in my 
prototypes and at one point it helped with performance, but I don't know 
if it still does, especially with our custom model.


3.3.3 Speed Issues when Adding a Lot of Rows

A common scenario is that a model needs to be filled with a lot of rows 
at some point, either at start-up, or when some file is opened. An 
equally common scenario is that this takes an awfully long time even on 
powerful machines once the model contains more than a couple of thousand 
rows, with an exponentially decreasing rate of insertion. As already 
pointed out above, writing a custom model might be the best thing to do 
in this case. Nevertheless, there are some things you can do to work 
around this problem and speed things up a bit even with the stock Gtk+ 
models:
