-*Peering Interval*
-  See PG::start_peering_interval.
-  See PG::acting_up_affected
-  See PG::RecoveryState::Reset
-
-  A peering interval is a maximal set of contiguous map epochs in which the
-  up and acting sets did not change.  PG::RecoveryMachine represents a 
-  transition from one interval to another as passing through
-  RecoveryState::Reset.  On PG::RecoveryState::AdvMap PG::acting_up_affected can
-  cause the pg to transition to Reset.

-Peering Details and Gotchas
----------------------------
-For an overview of peering, see `Peering <../../peering>`_.
-
-  * PG::flushed defaults to false and is set to false in
-    PG::start_peering_interval.  Upon transitioning to PG::RecoveryState::Started
-    we send a transaction through the pg op sequencer which, upon complete,
-    sends a FlushedEvt which sets flushed to true.  The primary cannot go
-    active until this happens (See PG::RecoveryState::WaitFlushedPeering).
-    Replicas can go active but cannot serve ops (writes or reads).
-    This is necessary because we cannot read our ondisk state until unstable
-    transactions from the previous interval have cleared.
