 The following hash algorithms are available:
 
+critbit 
+   A self-scaling tree structure. The default hash algorithm in
+    Varnish Cache 2.1 and onwards. In comparison to a more traditional
+    B tree the critbit tree is almost completely lockless. Do not 
+    change this unless you are certain what you're doing.
+
 simple_list
     A simple doubly-linked list.  Not recommended for production use.
 
 classic[,buckets]
-    A standard hash table.  This is the default.  The hash key is the
-    CRC32 of the object's URL modulo the size of the hash table.  Each
-    table entry points to a list of elements which share the same hash
-    key. The buckets parameter specifies the number of entries in the
-    hash table.  The default is 16383.
