// * CheckForStaleTipAndEvictPeers locks cs_main before indirectly calling GetExtraFullOutboundCount

// * ProcessMessage locks cs_main and g_cs_orphans before indirectly calling ForEachNode which
// locks cs_vNodes.
// * CConnman::Stop calls DeleteNode, which calls FinalizeNode, which locks cs_main and calls
// EraseOrphansFor, which locks g_cs_orphans.
