Perhaps we should just clear the bit in the function.
If that were to fix this test case, I think it would be incidental rather than meaning the right thing. The "this task wants single-stepping" state should not have anything to do with TIF_SINGLE_STEP. It means "this task recently had single-stepping", which is a separate moving part. Thanks, Roland
