3244 * scrubbed, potentially, when a peer is removed:
3246 * 1 peer's routes visible via the RIB (ie accepted routes)
3247 * 2 peer's routes visible by the (optional) peer's adj-in index
3248 * 3 other routes visible by the peer's adj-out index
3250 * 3 there is no hurry in scrubbing, once the struct peer is
3251 * removed from bgp->peer, we could just GC such deleted peer's
3252 * adj-outs at our leisure.
3254 * 1 and 2 must be 'scrubbed' in some way, at least made
3255 * invisible via RIB index before peer session is allowed to be
3256 * brought back up. So one needs to know when such a 'search' is
3261 * - there'd be a single global queue or a single RIB walker
3262 * - rather than tracking which route_nodes still need to be
3263 * examined on a peer basis, we'd track which peers still
3266 * Given that our per-peer prefix-counts now should be reliable,
3267 * this may actually be achievable. It doesn't seem to be a huge
3268 * problem at this time,
3270 * It is possible that we have multiple paths for a prefix from a peer
