* than strings also need to have a single or double linked list pointers
* for insertion into the "heap allocated" list. Strings are held in the
* heap-wide string table so they don't need link pointers.
*
* Technically, 'h_refcount' must be wide enough to guarantee that it cannot
* wrap (otherwise objects might be freed incorrectly after wrapping). This
* means essentially that the refcount field must be as wide as data pointers.
* On 64-bit platforms this means that the refcount needs to be 64 bits even
* if an 'int' is 32 bits. This is a bit unfortunate, and compromising on
* this might be reasonable in the future.
*
* Heap header size on 32-bit platforms: 8 bytes without reference counting,
* 16 bytes with reference counting.
