  "message": "gh-159538: Fix deep chain leak in test_deeply_dotted_name (#159576)\n\ntest_deeply_dotted_name() builds a 10,000-deep chain of lazy import\nplaceholders in a thread with a 256 KiB C stack.  Freeing the chain\nthere defers most deallocations to the trashcan, which only drains them\nonce the stack margin recovers.  With a stack that small the margin\nnever does, so the deferred objects were leaked when the thread exited,\nwhich -R reports as a reference leak on platforms with larger frames\nsuch as PPC64LE.\n\nClear the namespace in a cleanup, which runs on the main thread.",
