-	 * The viewer session's current trace chunk is initially set, when

-	 * A live session always attempts to "catch-up" to the newest available
-	 * trace chunk. This means that when a viewer reaches the end of a
-	 * trace chunk, the viewer session may not transition to the "next" one:
-	 * it jumps to the most recent trace chunk available (the one being
-	 * produced by the relay_session). Hence, if the producer performs
-	 * multiple rotations before a viewer completes the consumption of a
-	 * trace chunk, it will skip over those "intermediary" trace chunks.
-	 *
-	 * A viewer session updates its current trace chunk when:
-	 *   1) new viewer streams are created,
-	 *   2) a new index is requested,
-	 *   3) metadata is requested.
-	 *
-	 * Hence, as a general principle, the viewer session will reference the
-	 * most recent trace chunk available _even if its streams do not point to
-	 * it_. It indicates which trace chunk viewer streams should transition
-	 * to when the end of their current trace chunk is reached.
