I want to detach $thr_1 from $thr_2 when $timer is up. But it seems not work by following code.

Does anyone know how to achieve this function? Thanks very much! 

#! /usr/bin/perl
use warnings;
use strict;
use threads;

my $thr_1;
my $thr_2;
my $timer = 3;
my $res;

$thr_1 = threads->new('func_thr_1');
$thr_2 = threads->create('func_thr_2');

$res = $thr_1->join();
print "exit code is: $res\n";

print "\nend\n";

sub func_thr_1 {
    my $cc = 0;
    print "thread 1 is running\n";
    while ($cc <= 10) {
        print "cout is $cc\n";
        sleep 1;
        $cc++;
    }
    return 'success';
}

sub func_thr_2 {
    while ($timer >= 0) {
        $timer--;
        sleep 1;
    }
    $thr_1->detach();
    print "\nTime up\n";
}
