4703 | * 3 there is no hurry in scrubbing, once the struct peer is | |

4708 | * invisible via RIB index before peer session is allowed to be | |
4709 | * brought back up. So one needs to know when such a 'search' is | |
4710 | * complete. | |

4712 | * Ideally: | |
4713 | * | |
4714 | * - there'd be a single global queue or a single RIB walker | |
4715 | * - rather than tracking which route_nodes still need to be | |
4716 | * examined on a peer basis, we'd track which peers still | |
4717 | * aren't cleared | |
4718 | * | |
4719 | * Given that our per-peer prefix-counts now should be reliable, | |
4720 | * this may actually be achievable. It doesn't seem to be a huge | |
4721 | * problem at this time, | |
4722 | * | |
4723 | * It is possible that we have multiple paths for a prefix from | |
4724 | * a peer | |
