// = TITLE
// 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.
