       *
       * Overview: There are 3 different indices which need to be
       * scrubbed, potentially, when a peer is removed:
       *
       * 1 peer's routes visible via the RIB (ie accepted routes)
       * 2 peer's routes visible by the (optional) peer's adj-in index
       * 3 other routes visible by the peer's adj-out index
       *
       * 3 there is no hurry in scrubbing, once the struct peer is
       * removed from bgp->peer, we could just GC such deleted peer's
       * adj-outs at our leisure.
       *
       * 1 and 2 must be 'scrubbed' in some way, at least made
       * invisible via RIB index before peer session is allowed to be
       * brought back up. So one needs to know when such a 'search' is
       * complete.
       *
       * Ideally:
       *
       * - there'd be a single global queue or a single RIB walker
       * - rather than tracking which route_nodes still need to be
       *   examined on a peer basis, we'd track which peers still
       *   aren't cleared
       *
       * Given that our per-peer prefix-counts now should be reliable,
       * this may actually be achievable. It doesn't seem to be a huge
       * problem at this time,
