> That brings us back to the original question: what limit should we use? I suggest we use a smaller number since normal tree should never be very tall. Running the following code tells me the height of the tree for xdisp.c is 30:
> 
> (defun measure-height (node)
>   (let ((children (treesit-node-children node t)))
>     (if children
>         (1+ (apply #'max (mapcar #'measure-height children)))
>       1)))
> ;; In xdisp.c:
> (measure-height (treesit-buffer-root-node))
> 
> Maybe a limit in the range of hundreds or thousands? 800?

I suggest 1000.
