??? wtf? You really miss the main point of multiple thread!

The cool thing about threads is that they run in parallel and do not per se 
rely on each other. Only this allows true distribution of the workload.

As soon as you start accessing the same data-structures from multiple threads, 
you have to start some locking. But the less locking you need, the better. 
That is why some projects rely on lock-free ring-buffers for communication 
between two threads.
If your locking is so heavy, that only one of the threads can run at a time, 
you can easily drop the threads...
