Martin, 

Assume you do next:

On func

    curs1 = select * from T

    ...

    // here curs1 must die to unlock records for next cursor.
    curs1 = VOID

    curs2 = select * from T WHERE ...

    // here we can skip explicit deletion, because at the end of
    // function cursor will be destroyed self by director.
end    


Of course usually developers do not create 2 cursors in the same function.
