  // The SplitWord construct allows us to colocate the contention queue
  // (cxq) with the lock-byte.  The queue elements are ParkEvents, which are
  // always aligned on 256-byte addresses - the least significant byte of
  // a ParkEvent is always 0.  Colocating the lock-byte with the queue
  // allows us to easily avoid what would otherwise be a race in lock()
