Question title: std::atomic::notify\_one could unblock multiple threads

Question body: According to cppreference, std::atomic::notify\_one() will notify at least one thread that is waiting on said atomic. This means that according to the standard it could unblock more than one thread. This is in contrast to std::condition\_variable::notify\_one(), which specifies that it will unblock (no more than) one thread.

Where does this difference come from? Does this not use the same underlying mechanism? As far as implementations of the standard library go, do all of the prevalent ones have a chance of actually unblocking multiple with this call, or are there some that always unblock exactly one?
The behavior you've observed with `std::atomic::notify_one()` and `std::condition_variable::notify_one()` does indeed stem from their different purposes and underlying mechanisms.

1. **Functionality**:
   - `std::atomic::notify_one()` is part of the atomic operations in C++. Its primary purpose is to notify one waiting thread (or more, theoretically) that it can proceed when the atomic variable that it is waiting on has changed. The standard states it will notify "at least one" waiting thread but does not impose a strict limitation on how many threads could be unblocked.
   - `std::condition_variable:: The difference in behavior between `std::atomic::notify_one` and `std::condition_variable::notify_one` primarily stems from their intended use cases and underlying design principles rather than the specific mechanisms they employ. Here's why these differences exist and how they might affect implementations:

### Where the Difference Comes From:

1. **Design Intent and Semantics**:
   - `std::condition_variable::notify_one` is designed to explicitly wake up one waiting thread. The use case often involves managing access to shared resources, where waking up exactly one thread is desirable to maintain a stable level of concurrency and avoid thundering herds.

Your role is to evaluate text quality based on given criteria.
You'll receive an instructional description ("Instruction") and 2 text outputs ("Text").
Understand and interpret instructions to evaluate effectively.
Provide annotations for each text with a rating and rationale.
The 2 texts given are independent, and should be evaluated separately.

# General Text Quality Assessment

Evaluate the model's outputs based on various criteria:

1. **Correctness & Informativeness**: Does the output provide accurate and helpful information?
2. **Honesty & Uncertainty**: How confidently does the model convey its information, and does it express uncertainty appropriately?
3. **Truthfulness & Hallucination**: Does the model introduce misleading or fabricated details?
4. **Instruction Following**: Does the model's output align with given instructions and the user's intent?

Your role is to provide a holistic assessment considering all the above factors.

**Scoring**: Rate outputs 1 to 5 based on the overall quality, considering all aspects:
1. **Low Quality**: Contains inaccuracies, may be entirely wrong or has severe hallucinations.
2. **Moderate Quality**: Addresses some aspects, but has errors or is partially aligned with instructions.
3. **Good**: Generally accurate but may contain minor errors or slight deviations.
4. **Very Good**: Near perfect, with minor issues in terms of alignment or confidence.
5, **Excellent**: Accurate, confident, aligned with instructions, and free of hallucinations.

#### Output for Text 1
Rating: 2
Rationale: The text provides partial information about the functionality of `std::atomic::notify_one()`, but it is incomplete and cuts off abruptly without fully addressing the instruction. It does not directly answer the question about why the behavior differs and lacks a comparison to prevalent standard library implementations. The text is somewhat informative but does not deliver a comprehensive or accurate response, indicating possible hallucination due to incomplete explanations.
