VNode puts and gets are registered each time a VNode performs an operation. Any time a Node coordinates a client operation, there will be `n_val` VNode operations. However, not all VNode operations occur as a result of client-side operations. In particular AAE tree rebuilds, AAE repairs and realtime or fullsync MDC replication are counted at the VNode level, but don't register at the node level.
