Why do we have two different cleanup functions here? It seems overly subtle
that `deallocate_contents` only calls `release_C_heap_structures_internal`,
rather than `release_C_heap_structures`. And now the only difference is whether
`constants()->release_C_heap_structures()` is called, it seems to me that
distinction should perhaps be more explicit in the caller.
