It seems I really do not need to worry too much because
if I understood it correctly the memory of the variable at
the end of the execution of that code is not only released
but it is also deleted.  Since the variable I am concerned
about is used at the end of the code it does not exist after
I use it because the code is finished and the memory is
automatically freed and deleted.
