| * Common heap header |
| * |
| * All heap objects share the same flags and refcount fields. Objects other |
| * 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. |
