the free area cache either is historically tricky to be fair; it has the
thankless job of either keeping at the "ealiest" small hole (and thus being
useless if most allocs are bigger than that hole) or leaving an occasionally
small hole alone and thus fragmenting memory more, like you've shown.
I like neither to be honest; the price however is a higher lookup cost (well
mitigated if vma merging is really effective)
