There may be other lists that keep track of those buffers...

Try evaling the following and post the list appearing in *Messages*:

(mapatoms
 (lambda (symbol)
   (when (boundp symbol)
     (let ((value (symbol-value symbol)))
       (while (consp value)
	 (let ((elem (car value)))
	   (when (bufferp elem)
	     (message "%s has a buffer %s"
		      symbol (buffer-name elem))))
	 (setq value (cdr value))))))
 obarray)
