It's not.  The cycbuff doesn't go back and use space until it rolls over
and the whole cycbuff starts being reused.

Nope.  It's exactly the same from a storage perspective as if you hadn't
cancelled the article.  The only thing that ctlinnd cancel does is remove
the article from overview and hide it from clients.
