When program terminate, asyncio:Unclosed client session

[zpoint]

Just instantiate Elasticsearch

es = Elasticsearch(["localhost:8000"])

When terminate:

Unclosed client session client_session: <aiohttp.client.ClientSession object at 0x7f64807de208>

Should aioes->connection.py->class Connection has a destructor ?

`

   def __del__(self):
          self._session.close()

`

aiohttp (2.0.4)
