There is currently a relatively fast memory leak when using cpython 3.11.2+ and cleanup_closed with aiohttp For my production instance it was leaking ~450MiB per day of `MemoryBIO`, `SSLProtocol`, `SSLObject`, `_SSLProtocolTransport` `memoryview`, and `managedbuffer` objects see aio-libs/aiohttp#7252 see python/cpython#98540
