+  //   A Data_Block with a concrete locking strategy.
+  //
+  // = DESCRIPTION
+  //   Data_Blocks can be parametric on the kind of lock they use; in
+  //   many cases the lifetime of the lock is tied to the lifetime of
+  //   the Data_Block itself. But since Data_Blocks are reference
+  //   counted it is hard for users to control the lock lifetime.
+  //   This class is parametric over the kind of lock used.
+  //
