Pytest hangs when using faulthandler_timeout with pytest-forked

[tykurtz]

Steps to reproduce

Create two files in root workspace

# foo.py
def test_bar():
    fjaoisjdfoiajsdofi

# pyproject.toml
[tool.pytest.ini_options]
faulthandler_timeout=1800

Create a minimal venv with pytest-forked

mkvirtualenv foo --python 3.7
pip install pytest-forked==1.3.0

Run the following,

pytest foo.py --forked

pytest should hang indefinitely during collection

Hey @tykurtz, thanks for reporting this! The plugin is not actively maintained so it's unlikely that anybody will start debugging this anytime soon. But if you're able to come up with a test that catches this, and a bugfix on top of that, feel free to send a PR and I'll try to find some time to review+merge that.
