- follow up locks and fix them - chainManager: call SetQueued for parentErr future blocks, uncomment TD checks, unskip test - make ErrIncorrectTD non-fatal to be forgiving to genuine mistaken nodes (temp) but demote them to guard against stuck best peers. - add purging to bounded nodeCache (config nodeCacheSize) - use nodeCache when creating blockpool entries and let non-best peers add blocks (performance boost) - minor error in addError - reduce idleBestPeerTimeout to 1 minute - correct status counts and unskip status passing status test - glogified logging
