Bug Description

In r5192 the transform code was changed from using os.rename to osutils.rename which boils down to no change on nix, but to _win32_rename to fancy_rename on windows.

This made the following tests no longer pass on windows:

The new test added in r5228 also fails:

The particular issue seems to be a difference in directory renaming. Given two directories, d1 and d2, rename(d1, d2) behaviour is as follows:

On nix with os.rename:
  d1 replaces d2, unless d2 has contents, in which case ENOTEMPTY is raised

On windows with os.rename
  EEXIST is raised

On windows with osutils._win32_rename:
  d2 is renamed to a temp name, d1 is renamed d2, and os.unlink throws EACCES

Need to never be using _win32_rename with directories, or teach it how to handle them.
