   1. Closes the specified boot script table
   2. It allocates a new memory pool to duplicate all the boot scripts in the specified table.
      Once this function is called, the table maintained by the library will be destroyed

   3. Any attempts to add a script record after calling this function will cause a new table

      by this function.
