If it isn't leaking in 3.8 then it's possibly not disposing of the event loop (I added a check for that in 8425de4#diff-226dcee10b9d2f379e54d4415489236f ).

Sadly, without much information, it's hard to guess what leaked nor if the issue has been fixed in the meanwhile. So I close the issue as outdated.

I just found a leak in test_asyncio ProactorLoopCtrlC and I proposed a fix: https://bugs.python.org/issue37278
