Why do you think it isn't reclaimed?

AFAIU, the issue was to explain why the memory footprint grows,
nothing was said about how much of that memory is free for reuse.  My
point is that activating the undo-list would use more of the "normal"
heap memory, in contrast to using only/mostly buffer text memory
without that.
