+ * THREAD_AFFINITY_POLICY:
+ *
+ * This policy is experimental.
+ * This may be used to express affinity relationships
+ * between threads in the task. Threads with the same affinity tag will
+ * be scheduled to share an L2 cache if possible. That is, affinity tags
+ * are a hint to the scheduler for thread placement.
+ *
+ * The namespace of affinity tags is generally local to one task. However,
+ * a child task created after the assignment of affinity tags by its parent
+ * will share that namespace. In particular, a family of forked processes
+ * may be created with a shared affinity namespace.
+ *
+ * Parameters:
+ * tag: The affinity set identifier.
