Maybe there is a way > to do this in-place? Not really. At least I do not recall malloc implementations being optimized for shrinking smaller allocations with realloc. For multi-page allocations, there's mremap(2), so it's not appropriate for most Ruby arrays (and also Linux-specific). Anyways, I like the rest of your changes to remove mark_ary and flagging markability.
