[3.12] gh-77377: Ensure multiprocessing SemLock is valid for spawn-based Process before serializing it (GH-107275) (#108377)
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.
