File descriptors and screen and you

I have a bit of perl code that I'm trying to make work:

sub DB::get_fork_TTY {

open my $SCREEN, qq{&3>1 screen -t 'Child $$' sh -c "tty &1>3 ; sleep 1000000" |}
    or return '';

  my $tty = <$SCREEN>;

  return $tty;

I'm getting bad file descriptor errors, so I'm assuming screen is cleaning up what it hands to it's children. Which makes sense.

I want to avoid going the tmp file route if at all possible. Is there a way I can echo tty's output so that I can grab it from a filehandle?

I've tried a number of different methods.

Any pointers?
