True. One further question though.

Why does using sort{ $a <=> $b } @numbers also cause the memory growth. The same appears to be true for Sort::Key::nsort(_inplace)?

Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
