Asyncio get_event_loop without current loop deprecated

[pintert3]

Version: 4.4.0

Platform: 3.10, Arch Linux

Description:

Asyncio gives a DeprecationWarning because of line 535 of connection.py:

loop = asyncio.get_event_loop()

It says there's no current event loop. From my little research it's expected that this line will throw an error in python 3.11 when called without a running loop in the current thread, according to this stackoverflow answer.

@pintert3 Thanks for reporting this. I fixed it in #2530
