When $opts{STDERR} is 2, what the three lines the proposed patch
removes did is actively wrong, because you dup2 the fd you just
closed.
When $opts{STDERR} is 1, it seems to do the right thing with or
without the "close STDERR" in front. Isn't this because the usual
"open($fd, <<<anything>>>) closes $fd as necessary" applies to this
case as well?
So, I am not sure what you are viewing as a problem. Puzzled...
