701cdbb6 - FIX make sure we import the correct object from multiprocessing (#81862)

FIX make sure we import the correct object from multiprocessing (#81862) Fixes #44687. The issue was that the Process object is not the one from the `_default_context` which should be `loky` when nesting `loky` calls. This is a revamp of #53282 that was reverted because it broke some other tests. How can I run the failing tests so I can see why this breaks?
