Here's some working queuer/consumer code based on Thread::Queue. Hope it helps.~

#!/usr/bin/perl
use threads;
use threads::shared;
use Thread::Queue;

my $q : shared;
use constant FINISH => 'finish';
main();
exit 0;

sub main {
    $q = Thread::Queue->new();

    my $queuer = threads->create('queuer', 10);
    my $worker = threads->create('worker');

    $queuer->join;
    $worker->join;
    print "main thread finished\n";
}

sub queuer {
    my $numItems = shift;
    my $str = "foo";
    while ($numItems-- > 0) {
        print "queueing $str\n";
        $q->enqueue($str);
        $str++;
        sleep 1;
    }
    $q->enqueue(FINISH);
    print "queuer finished\n";
}

sub worker {
    DOING_WORK:
    while (1) {
        while (my $pending = $q->pending) {
            my $str = $q->dequeue;
            print "worker found $pending items, got $str\n";
            last DOING_WORK if $str eq FINISH;
        }
        sleep 3;
    }
    print "worker finished\n";
}
