// TODO: Remove NO_THREAD_SAFETY_ANALYSIS. Lock cs_vNodes before reading the variable vNodes.
//
// When removing NO_THREAD_SAFETY_ANALYSIS be aware of the following lock order requirements:
// * CheckForStaleTipAndEvictPeers locks cs_main before indirectly calling GetExtraOutboundCount
// which locks cs_vNodes.
// * ProcessMessage locks cs_main and g_cs_orphans before indirectly calling ForEachNode which
// locks cs_vNodes.
//
// Thus the implicit locking order requirement is: (1) cs_main, (2) g_cs_orphans, (3) cs_vNodes.
