I don't know what the "consing" means here. I only know that `cons' is often
used to add a single element to the front of a list. But this seems to be
irrelevant to the topic.
And in (info "(elisp) Garbage Collection"):
-- Function: memory-use-counts
This returns a list of numbers that count the number of objects
created in this Emacs session.
Does "consing" mean creating an object here? Thanks.
Yes: allocating a cons cell.
