(mapatoms (lambda (s) (incf n))) tells me I have 43061 symbols defined.
(length obarray) tells me the standard obarray has a size of 1511.
My understanding is that an obarray is essentially a hash table with
collision chaining. But this would mean that the linked list of symbols
in each bucket has an average length of 43061 / 1511 ≈ 28.
Emacs's symbol lookup couldn't possibly be that inefficient, could it?
