Bug report

Bug description:

Ubuntu 22.04
python 3.12, python3.11

import ssl import socket import time host = '192.168.16.66' # some server we can connect with https as example port = 443 session = None context = ssl._create_unverified_context(protocol=ssl.PROTOCOL_TLSv1_2) with socket.create_connection((host, port)) as sock: with context.wrap_socket(sock, server_hostname=host, session = session) as ssock: for i in range(300000): session = ssock.session print('Sleeping') time.sleep(200)

Here is part of script that is used for "ssl reuse" session during connection to server
Running this script brings to memory leak (process memory increased from 322Mb to 2.5Gb).
Memory is not freed on "time.sleep" instruction
Not reproduced on python 3.8

CPython versions tested on:

3.11, 3.12
