@Migueldeicaza I checked the memory usage of emacs and emacs itself uses 6 MiB of memory sitting on the start screen, editing a file or running emacs tetris - so emacs doesn't even use 8 MiB still.

With all the dynamically linked GtK libraries included it works out to ~170MiB of memory, but some of that is cache, plus that isn't really part of emacs - the libraries are in use by other programs already, so launching emacs barely increases the memory used (plus I have ~64 billion bytes of it).
