I use the technique you described in all my notebooks, with a wide range 
of pages, and it works fine. However I don't have textviews. This is a 
textview problem I guess. And probably there is a simple solution. You 
need to apply gtk_widget_size_request AFTER all your pages and notebook 
window are visible and realized, otherwise GTK does not know the size of 
things. And if you fixed the size of your textview widgets, it should in 
theory be [simple,possible] to come to a maximum size for the notebook...
