TLS/SSL asyncio/uvloop leaks memory

python3.9 or uvloop seems to leak smaller, but python3.11 (and others?) leaks A LOT OF memory under load
test command: ab -n15000 -c15000 -r https://127.0.0.1/
(apt install apache2-utils)

```
import asyncio, ssl, uvloop

class HTTP(asyncio.Protocol):

def __init__(self):
self.transport = None

def connection_made(self, transport) -> None:
self.transport = transport

def data_received(self, data) -> None:
self.transport.write(
b'HTTP/1.1 200 OK\r\nContent-Length: 0\r\nConnection: keep-alive\r\n\r\n'
)
self.transport.close()

def connection_lost(self, _=0) -> bool | None:
self.transport.close()

def make_tls_context():
ctx = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
ctx.load_cert_chain('cert.crt', 'cert.key')
return ctx

tls_context = make_tls_context()
loop = uvloop.new_event_loop()
loop.set_debug(True)

async def start_server(loop):
return await loop.create_server(
HTTP, '127.0.0.1', 443, backlog=65535,
ssl=tls_context)

loop.run_until_complete(start_server(loop))
loop.run_forever()
loop.close()
```

CPython versions tested on:
3.9, 3.11

Operating systems tested on:
Linux

Start with the minimal asyncio.Protocol reproducer using uvloop.new_event_loop, loop.create_server, and the TLS context, then run the provided ab -n15000 -c15000 -r command on Linux across the reported Python versions. Compare memory behavior with and without TLS and uvloop; done means the leak is isolated and memory no longer grows excessively under the reproduced load.
