+ *
+ * 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,
