I have a threaded program with queue implemented as an array of arrays (I need the possibility to insert commands in the middle of the queue sometimes, so the Thread::Queue doesn't fit.) However, when I add to the queue, it doesn't stick. Here's where I insert the things in the queue: 
sub queuecommand {
    my ($mcvpservers, $cmd, $priority, $server, $file, $time) = @_;
    my @tmp : shared;
    @tmp = ($cmd, $priority, $server, $file, $time);
    my @queue = $mcvpservers->{$server}->[2];
    print $#queue+1;
    if ($#{$queue[0]}+1 == 0)
    {   
        push @queue, \[@tmp];
    }
    else
    {
        for(my $i = 0; $i < $#queue+1; $i++)
        {
            if ($priority > $queue[$i][1])
            {
                splice @queue, $i, 0, \[@tmp];
                last;
            }
        }
    }
    print $#queue+1;
}

The $mcvpservers is a hash_ref with a queue at the 2 index. I have created the queue as a shared: our @queue : shared = (); Everytime I enter the queuecommand, my queue is empty. What have I done wrong?
