It's not actually hard. The system has threads that are fed off a Thread::Queue. Each thread takes a job from the queue, performs it, then takes the next one from the queue. The map just creates $T threads, and to tell each thread that it is finished, it sticks $T undef elements at the end of the queue. Then the main thread waits that all threads finish their work. That's all there is to it.
