Research direction

Start with the uploaded reproducers s03_dir_entry.py and inspect the os.scandir() and DirEntry.stat() behavior they exercise on Windows while a file is being written. Reproduce the failure first; done means the reported stat() failure is resolved and the behavior is covered by an appropriate regression test.
