[PyQt5] Memory leak when trying to connect to a server that does not work without SSL

[tretdm]

Strange situation however even with tracemalloc (without specifying "Only SSL/TLS"). Therefore, because of this, it is difficult for me to figure out the cause of the memory leak.

UPD: I tried connect to irc.gramsk.ru:6666 server without specifying "Only SSL/TLS", there is no memory leak here.

Information about my testing:
Python 3.9.5 (2021-07-12), PyQt 5.15.4 (connection is made through a separate QThread and socket module), Qt 5.15.2, Linux 5.10.42 with PREEMPT

The trick is that, this memory leak doesn't happen on Windows.
