// SUBTLETY TO DO WITH THE OLD GEN MUTABLE LIST
//
// A MUT_ARR_PTRS lives on the mutable list, but a MUT_ARR_PTRS_FROZEN
// it on the mutable list for the GC to remove (removing something from
// the mutable list is not easy, because the mut_list is only singly-linked).
//
+ // So that we can tell whether a MUT_ARR_PTRS_FROZEN is on the mutable list,
+ // when we freeze it we set the info ptr to be MUT_ARR_PTRS_FROZEN0 to indicate
+ // that it is still on the mutable list.
+
// So, when we thaw a MUT_ARR_PTRS_FROZEN, we must cope with two cases:
// either it is on a mut_list, or it isn't. We adopt the convention that
// the mut_link field is NULL if it isn't on a mut_list, and the GC
// maintains this invariant.
