No. That's the code that's currently running. See here for the error: http://lab.llvm.org:8011/builders/clang-with-thin-lto-windows/builds/8570/steps/stage%202%20clean/logs/stdio

I tested the code on the affected machine. shutil.rmtree fails with the permissions error. The rmtree implementation I wrote succeeds.
