Yes, but the CHMs used in the nodes to hold children don't use the default 16 segments:


  | 
  |             // Less segments to save memory
  |             children = new ConcurrentHashMap<Object, Node<K, V>>(4, .75f, 4);
  | 

Ah, but the LockMaps do!!  Each LockMap - used to hold information on concurrent readers when using pessimistic locking - uses a ConcurrentHashSet, which is a wrapper around a CHM that implements Set.
