One of the things I have decided to check is what I am doing with 
vectors because more than 2M vector slots were being locked up in an 
empty Emacs session.

A widespread use of vectors in VM is for obarrays.  The code might look 
something like this:

   (let ((obarray (make-vector 67 0)))
      ... intern lots of symbols in obarray
      (setq buffer-local-var obarray))

I have begun to wonder if obarray gets freed after buffer-local-var 
stops pointing to it, say through another setq to buffer-local-var.

Am I supposed to unintern the symbols to free up their memory?

Cheers,
