-  //     A Singleton Adapter the uses the Adapter pattern to turn

-  //     Double-Checked Locking optimization pattern.

-  // = DESCRIPTION
-  //     This implementation is a slight variation on the GoF
-  //     Singleton pattern.  In particular, a single
-  //     <ACE_Singleton<TYPE, LOCK> > instance is allocated here, not
-  //     a <TYPE> instance.  The reason for this is to allow
-  //     registration with the <ACE_Object_Manager>, so that the
-  //     Singleton can be cleaned up when the process exits.  For this
-  //     scheme to work, a (static) <cleanup> function must be
-  //     provided.  <ACE_Singleton> provides one so that TYPE doesn't
-  //     need to.

-  // = TITLE
-  //     This class uses the Adapter pattern to turn ordinary classes
-  //     into Thread-specific Singletons optimized with the
-  //     Double-Checked Locking optimization pattern.
-  //   
-  // = DESCRIPTION
-  //     This implementation is another variation on the GoF Singleton
-  //     pattern.  In this case, a single <ACE_TSS_Singleton<TYPE,
-  //     LOCK> > instance is allocated here, not a <TYPE> instance.
-  //     Each call to the <instance> static method returns a Singleton
-  //     whose pointer resides in thread-specific storage.  As with
-  //     <ACE_Singleton>, we use the <ACE_Object_Manager> so that the
-  //     Singleton can be cleaned up when the process exits.  For this
