Pylint crashes with pylint_pytest & jobs>1 specification & `global` definition

[martinky24]

Describe the bug
Pretty straightforward. If I have

1. a global variable
2. jobs > 1
3. pylint_pytest as an enabled plugin

I get a flurry of exceptions, seemingly starting with a RecursionError: maximum recursion depth exceeded in comparison.

To Reproduce
Package versions

$ pip freeze
astroid==3.3.11
dill==0.4.0
exceptiongroup==1.3.0
importlib_metadata==8.7.0
iniconfig==2.1.0
isort==6.1.0
mccabe==0.7.0
packaging==25.0
platformdirs==4.4.0
pluggy==1.6.0
pylint==3.3.9
pylint-pytest==1.1.8
pytest==8.2.0
tomli==2.2.1
tomlkit==0.13.3
typing_extensions==4.15.0
zipp==3.23.0

$ python --version
Python 3.9.20

File content

.pylintrc:

[MASTER]
load-plugins=pylint_pytest
jobs=4

my_file.py:

def mainroutine():
    global foo


if __name__ == "__main__":
    mainroutine()

Pylint output with the plugin

Expected behavior
No crash!

After filing, I stumbled upon the closed issue #56

I tested against pylint-pytest-2.0.0a0 and I no longer see the crash.
