// G4AutoDelete
//
// Description:
//
//   This function implements a simplified "garbage collection" mechanism
//   for G4-MT model. Objects are registered when created on the heap and they
//   will be deleted at the end of the program (like they would be if marked
//   as "static").
//
// Limitation:
//   The registered object, should not contain any G4ThreadLocal data member.
//   Note that in general, if object is to be thread-private it is unnecessary
//   to mark any data-member as G4ThreadLocal.
//
// Performance issues:
//   This function uses G4ThreadLocalSingleton that on its own uses
//   locks and mutexes. Thus its use should be limited to only when
//   really necessary.
//
// Example:
//   class G4SharedByThreads
//   {
//     void calledByThreads()
//     {
//       G4Something* anObject = new G4Something;
//       G4AutoDelete::Register( anObject );
//     }
//   }
