Depends - on a copying garbage collector it doesn't matter. Allocation
happens by moving a pointer and deallocating happens by copying objects that
are still in use. Of course Ruby's garbage collector isn't copying. OCaml
uses a mixture where the young generation is copying and the old generation
is mark sweep. (Young survivors are copied into the mark/sweep heap).
