  HAMMER 61B/Many: Stabilization
  
  * Giving the sync_lock's exclusive locks priority over shared locks caused
    a 3-way deadlock, revert to using normal shared locks.
  
  * Move the syncer_lock deeper, closer to the code that actually needs to
    hold but still paying attention to atomicy requirements.  This reduces
    lock contention and improves performance with parallel loads.
