Re: [boost] [thread][thread_specific_ptr]

      ...
boost::thread_specific_ptr acts as a pointer rather than a value.
It will start out as a null pointer in each thread.  You can test
whether it has been set to something else with
if(tls_3.get() != 0)

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.
