* @class ACE_Locked_Data_Block
*
* @brief A Data_Block with a concrete locking strategy.
*
* 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.
