   > Looks good to me. Although I'm curious to know: if a path is updated on a frequent interval which is less than the TTL, its stale versions will steadily grow in size. Is that a case we would worry about?
   
   The TTL design is to prevent GC a node that might being accessed by other threads/nodes. If update is frequent, then we may have multiple version during the TTL window. But they will eventually be cleaned up.
