    hammer2 - Change from splay -> red-black tree
    
    * Even though splay trees are faster they are not lookup-safe under a
      shared lock.  In order to consolidate the chain locks with the cache
      coherency state we need to make lookups shared-safe.
    
    * This will allow me to move chain locks from exclusive to shared/exclusive
      with only modest surgery.
