Do you see something > different on X? In that e-mail, I reported about ~360M RSS usage reduced to ~150M. In http://lists.gnu.org/archive/html/emacs-devel/2013-10/msg00750.html, Stefan has confirmed ~300M RSS usage. Although things like bloat-font aren't typical use cases, holding ~200M which we can't reuse is worth trying to fix, IMHO. Dmitry
