+ * tree root) directly point to stored pointers.
+ *
+ * The index is valid if and only if the parent isn't NULL.
+ *
+ * Concerning the allocation bitmap, a bit is set when the node it denotes,

+ * is clear when the matching node and all of its children have no free entry.
+ *
+ * In order to support safe lockless lookups, in particular during a resize,
+ * each node includes the height of its subtree, which is invariant during
+ * the entire node lifetime. Since the tree height does vary, it can't be
+ * used to determine whether the tree root is a node or a stored pointer.
+ * This implementation assumes that all nodes and stored pointers are at least
+ * 4-byte aligned, and uses the least significant bit of entries to indicate
+ * the pointer type. This bit is set for internal nodes, and clear for stored
+ * pointers so that they can be accessed from slots without conversion.
