No, it's just that Emacs' image cache is very primitive. You can easily
get Emacs to go out-of-memory by just doing a
(dolist (file (directory-files dir-with-lots-of-images))
(erase-buffer)
(insert-image (create-image file)))
You get the same effect by altering the scaling factor, I think? Each
scaled image is cached? So by rolling the wheel ten clicks you get ten
cached copies of the image.
A better eviction algorithm would be nice.
