This reverts commit 57f27e4441.
The fix caused gh-107940. Until we have a bulletproof fix for that, the 3.11 backport needs to be reverted to make way for 3.11.5.
* In preauth tests of test_ssl, explicitly break reference cycles
invoving SingleConnectionTestServerThread to make sure that the
thread is deleted. Otherwise, the test marks the environment as
altered because the threading module sees a "dangling thread"
(SingleConnectionTestServerThread). This test leak was introduced
by the test added for the fix of issue gh-108310.
* Use support.SHORT_TIMEOUT instead of hardcoded 1.0 or 2.0 seconds
timeout.
* SingleConnectionTestServerThread.run() catchs TimeoutError
* Fix a race condition (missing synchronization) in
test_preauth_data_to_tls_client(): the server now waits until the
client connect() completed in call_after_accept().
* test_https_client_non_tls_response_ignored() calls server.join()
explicitly.
* Replace "localhost" with server.listener.getsockname()[0].

gh-77377: Ensure multiprocessing SemLock is valid for spawn-based Process before serializing it (GH-107275)
Ensure multiprocessing SemLock is valid for spawn Process before serializing it.
Creating a multiprocessing SemLock with a fork context, and then trying to pass it to a spawn-created Process, would segfault if not detected early.

Explicitly break a reference cycle when SSLSocket._create() raises an
exception. Clear the variable storing the exception, since the
exception traceback contains the variables and so creates a reference
cycle.
This test leak was introduced by the test added for the fix of GH-108310.

gh-108267: Dataclasses docs: Fix object.__setattr__ typo (GH-108355)
Fixed a sentence in dataclasses.rst
Changed "__setattr__" to "object.__setattr__" in a section that was specifically supposed to refer to the __setattr__ method of the object class. Also suppressed the link to the data model docs for __setattr__, since we're talking about a specific __setattr__ implementation, not __setattr__ methods in general.

When changing docs, it was easy to find text in topics.py, and I
wondered whether I was supposed to edit it. Thankfully, the top of the
file says it's auto-generated, so I knew I didn't have to edit it. But I
didn't know what started the auto-generation process.
It's part of the release process, so I'll leave a note here for future
editors.

gh-108310: Fix CVE-2023-40217: Check for & avoid the ssl pre-close flaw
Instances of `ssl.SSLSocket` were vulnerable to a bypass of the TLS handshake
and included protections (like certificate verification) and treating sent
unencrypted data as if it were post-handshake TLS encrypted data.
The vulnerability is caused when a socket is connected, data is sent by the
malicious peer and stored in a buffer, and then the malicious peer closes the
socket within a small timing window before the other peers’ TLS handshake can
begin. After this sequence of events the closed socket will not immediately
attempt a TLS handshake due to not being connected but will also allow the
buffered data to be read as if a successful TLS handshake had occurred.

Clearly document the supported seek() operations:
- Rewind to the start of the stream
- Restore a previous stream position (given by tell())
- Fast-forward to the end of the stream
(Spawning subprocesses does not require the event loop to run in the main thread -- only signal handling does.)

gh-107396: tarfiles: set self.exception before _init_read_gz() (GH-107485)
In the stack call of: _init_read_gz()
```
_read, tarfile.py:548
read, tarfile.py:526
_init_read_gz, tarfile.py:491
```
a try;except exists that uses `self.exception`, so it needs to be set before
calling _init_read_gz().
