-** The main invariant of the garbage collector, while marking objects,
-** is that a black object can never point to a white one. Moreover,
-** any gray object must be in a "gray list" (gray, grayagain, weak,

-** the collection cycle. These lists have no meaning when the invariant
-** is not being enforced (e.g., sweep phase).
