Task information delay

ATM, when we do:

```python
fut = async_task()

print(fut.task)
```
We will get an attribute error as the `task` property will not be immediately available as we fire an `asyncio.create_task` so that we do not block the `event-loop`.


So the user might need to wait for `< 1s` to get the task info.

This might cause a race condition and needs to be pfixed appropriately
