No. But, to whom it may be interesting, running the following code:
 
(dotimes (n 10000)
  (let ((x (make-frame-on-display ":1.0"))
        (y (make-frame-on-display ":1.0")))
    (delete-frame x)
    (delete-frame y)))

with Xnest (which is ":1.0") successfully raises Emacs' RSS from
~30M to ~120M.
