I have a similar experience.

The case I described was real, although seldom happens here. I can think
of typical scenarios where buffer size grows to large sizes: ERC
sessions, files monitored with auto-revert(-tail)-mode... Even cases
where the user makes a mistake that creates huge buffers (visiting a
GNUs group with tens of thousands on unread messages, for instance.)
Taking a selfish stance, I don't care about this problem because it is
not harming me, but your response and Stefan's looks a lot like hand
waving. Yes, it probably is hard to fix and there are more profitably
tasks, but it *is* a real problem, not something a user made up for
chatting about memory allocators on emacs-devel.
