* background threads writing to stdout/stderr can cause children to deadlock if a thread in the parent holds the internal lock on the BufferedWriter wrapper
* prevent writes to std handles during fork by monkeypatching stdout/stderr during display startup to require a mutex lock with fork(); this ensures no background threads can hold the lock during a fork operation
* add integration test that fails reliably on Linux without this fix
* Add find_spec and exec_module to RestrictedModuleLoader
* Fix getting new loader with correct path
Fix pep8 errors
* Use convert_ansible_name_to_absolute_paths instead of the loader path
* Apply suggestions from code review
* Fix type hints and test them in CI
* Fix error message for ansible.module_utils.basic if it's missing
Add mypy ignored missing imports for controller sanity tests
* Add mypy attr-defined ignore entries for python 3.8, 3.9, 3.10 for vendored six
Add mypy attr-defined ignore for python 2.7 in lib/ansible/utils/collection_loader/_collection_finder.py
* Just test controller python versions to simplify ignoring mypy errors
* Implement find_spec and exec_module to remove reliance on deprecated methods in the collection loader
