API question: is it possible to distribute API calls to run simultaneously across multiple computing clusters? I wrote my code to do just this, but when two sessions run simultaneously, I get the following error:

connections: ['[(<aiohttp.client_proto.ResponseHandler object at 0x7f6e573b8ac0>, 17520463.43490926)]']
connector: <aiohttp.connector.TCPConnector object at 0x7f6e57d5d160>
Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0x7f6e573bc4f0>
Unclosed connector
2

as long as its under the rate limit (1k/min) then its fine. that error looks to be related python and asyncio.
