That crossed my mind as well.

Robert: this may be something to check when you're ready again: did you insert
gnc_suspend_gui_refresh and gnc_resume_gui_refresh calls at the right locations when 
switching cells ?

Without these calls there probably would be a whole explosion of gui refresh events while the 
model is being updated internally.

On the other hand it may also be that the GtkTreeView is slower than our highly optimized old 
register code. I remember a comment from Robert somewhere that he got good performance 
when limiting the number of entries in the register to 1000. I don't know how well 
GtkTreeView scales to large datasets.
