I was hoping for something that could show at least thousands of instances. Going one by one would be extremely time-consuming and potentially deceptive. Does Emacs zero-initialize memory when it is garbage-collected? Even if it doesn't, maybe it is enough to dump the whole image to a file. Some part would be gc-ed data, but a comparatively small part among all the rest of hundreds of MB.
