Description: Append items to the local list in a loop without a lock. Appending to the list without a lock can improve performance, but testing grp.getgrall() produced noisy results, making it difficult to determine any improvement. Running a micro benchmark with a function that adds over 100K items to the list using _PyList_AppendTakeRef() instead of PyList_Append() showed about a 35% performance improvement. cc: @mpage @colesbury Issue: gh-116738
