[BUG] Cannot import Astroid with schemathesis 3.19.6.

Describe the bug
When I start a pytest session the astroid package enters an infinite loop when it is imported.

To Reproduce
I prepared a pipenv file that creates an environment to reproduce the issues.

Once you downloaded all files run

1. make .venv
2. run-pipenv run python -m pytest t.py --pdb

This will drop you in a debugger session at the place where astroid is stuck in a loop. With version 3.19.0 everything still works.

Expected behavior

Adding schemathesis as a dependency has no impact if I can import astroid in a pytest environment or not.

Environment (please complete the following information):

• OS: linux
• Python version: 3.11
• Schemathesis version: 3.19.6

Additional context
I'm not sure what the root cause is so I will also open tickets for this with pytest and astroid.

Over in pytest-dev/pytest#11053 (comment), I bisected this to #1736 - apparently, doing something like:

from dataclasses import dataclass

print(type(__builtins__))
print(hasattr(__builtins__, "__builtins__"))

@dataclass
class Bla(Exception):

    __module__ = "builtins"

print(type(__builtins__))
print(hasattr(__builtins__, "__builtins__"))

causes a __builtins__.__builtins__ to appear out of nowhere, and that in turn causes astroid to choke. Why? No idea! But schemathesis seems to be out of the picture, unless you want to avoid this kind of pattern to work around this. But I suppose it should be fixed in astroid.

I think this should be fixed on the astroid side, going to close this one. Thank you for investigating and providing context!
