OSError have no include TimeoutError?

I found this error⬇️
```bash
Exception in thread Thread-1 (_thread_main):
Traceback (most recent call last):

return self._sock.recv(bufsize)
TimeoutError: [Errno 60] Operation timed out
```
and check the code:

```python
class ConnectionError(OSError): ...
```
**Looks fine, But it is none.
So I add this code:**

**It works.**

This is not the same as described in the previous issue #291 and #288 , why?
