Thanks for the wordy post , I understood the issue better now. Do we need threads If we serialize a move operation ? We can achieve the similar behaviour with a simple code below, 
@positions = qw/5 15/;

while (1) {
    for (@positions) {
        move($_, CONSTANT);
        addstr($Counter);
        $Counter++;
    }
}

But the  $Counter is same and we will have to write little complex code to use multiple counters. Then where do we really use threads in GUI Applications ?
