 * 
 * Implementations should adhere to the following:
 * 

 * contain a constructor accepting a single argument of type
 * {@link org.hibernate.engine.SessionFactoryImplementor}
 * 
should be thread safe
 * 
should be fully serializable
 * 
 * 
 * Implementors should be aware that they are also fully responsible for
 * cleanup of any generated current-sessions.
 * 
 * Note that there will be exactly one instance of the configured
 * CurrentSessionContext implementation per {@link org.hibernate.SessionFactory}.
