        .Description
        Executes a task with different calls in parallel.
        
        .Parameter TaskScript
        The script for the task to be executed.
        .Parameter Parameters
        An array of hash tables. Each hash table provides

        .Parameter Throttle
        The maximum number of parallel executions of this
        task.
        .Example
        $task_script = { 
            param($name, $age)
            "$name is $age years old." >> c:\"temp\${name}.txt"
