Oh, you are right: if I set garbage-collection-messages non-nil, I see a GC message each time I move the cursor. So I guess my original theory was probably wrong, and the actual suspect is some code, yet to be discovered, that conses such large amounts of Lisp data. I will look into it if no one beats me to it.
