**User's Concerns Analysis:**

The user has not clearly specified the concerns they have with the code. However, after analyzing the code, the following concerns can be identified:

1. The code is missing an import statement for the `math` module, which is required for the `math.sqrt()` function.
2. The queue is not being properly synchronized, which may cause unexpected behavior.
3. The code does not handle the scenario when the queue is empty and all worker threads have finished.
4. The code does not handle the termination of worker threads when there are no more items in the queue.
5. The code does not provide a way to gracefully terminate the program.

I will now inspect the code to identify any other issues and address the concerns mentioned above.
