This code segment functions to: Manage a thread-safe task processing system that executes functions asynchronously in a background thread while handling concurrency control and error logging for queued operations.

```python
[TASK_BEGIN]
class Listener:
    _task_queue = FIFOQueue()
    _thread_started = False

    @classmethod
    def _process_tasks(cls):
        while True:
            task = cls._task_queue.next()
            func, args, kwargs = task
            func(*args, **kwargs)

    @classmethod
    def add_task(cls, func, *args, **kwargs):
        if not cls._thread_started:
            thread = Thread(target=cls._process_tasks, daemon=True)
            thread.start()
            cls._thread_started = True
        cls._task_queue.push((func, args, kwargs))
