> A more principled solution might be to make buffers GC-able like any other object, at least optionally. Exactly how to do this can be discussed but maybe just being able to remove a buffer from Vbuffer_alist would do. (We have one buffer like that, Vprin1_to_string.) Of course, we'd have to teach the GC to destroy buffers. Fkill_buffer is depressingly long and complicated and should be broken up in smaller parts.

There's no way Emacs could know whether a buffer is still needed.
Users that want to get rid of buffers that were not accessed for too
long can use the midnight.el features to do that.  So I don't think we
need to add any automation here.
