+/** Round Robin Policy.
+ *
+ * This policy keeps:
+ * - A circular list of ready (connected) subchannels, the *readylist*. An empty
+ *   readylist consists solely of its root (dummy) node.
+ * - A pointer to the last element picked from the readylist, the *lastpick*.
+ *   Initially set to point to the readylist's root.
+ *
+ * Behavior:
+ * - When a subchannel connects, it's *prepended* to the readylist's root node.
+ *   Ie, if readylist = A <-> B <-> ROOT <-> C
+ *                      ^                    ^
+ *                      |____________________|
+ *   and subchannel D becomes connected, the addition of D to the readylist
+ *   results in  readylist = A <-> B <-> D <-> ROOT <-> C
+ *                           ^                          ^
+ *                           |__________________________|
+ * - When a subchannel disconnects, it's removed from the readylist. If the
+ *   subchannel being removed was the most recently picked, the *lastpick*
+ *   pointer moves to the removed node's previous element. Note that if the
+ *   readylist only had one element, this is still legal, as the lastpick would
+ *   point to the dummy root node, for an empty readylist.
+ * - Upon picking, *lastpick* is updated to point to the returned (connected)
+ *   subchannel. Note that it's possible that the selected subchannel becomes
+ *   disconnected in the interim between the selection and the actual usage of
+ *   the subchannel by the caller.
