- * can move around the object space. Our GC engine rearranges these objects
- * after it reclaims unreachable objects from our object space, so that the
- * space is compact (improves memory locality). This is called the
- * "compaction" phase, and works well most of the time... as far as there are
- * no C extensions. C extensions complicate the scenario because Ruby core
- * cannot detect any use of the physical address of an object inside of C
- * functions. In order to prevent memory corruptions, objects observable from
- * C extensions are "pinned"; they stick to where they are born until they die,
- * just in case any C extensions touch their raw pointers. This variant of
- * scheme is called "Mostly-Copying" garbage collector. Authors of C
- * extensions, however, can extremely carefully write them to become
- * compaction-aware. To do so avoid referring to a Ruby object from inside of
- * your struct in the first place. But if that is not possible, use this
- * function from your ::rb_data_type_struct::dmark then. This way objects
- * marked using it are considered movable. If you chose this way you have to
- * manually fix up locations of such moved pointers using rb_gc_location().
