I see. I have to give this class and its limitations some more thought.

For the time being, I see myself having to do that test before each usage of the globals.
ie.

    if ( tls_3.get() == NULL )  tls_3.reset( new int );
    *tls_3 = 999;

This kind of coding can get expensive if used constantly in that manner.
