With the patch applied, the new test fails along with test.test_os.WalkTests.test_traversal and test.test_os.Win32SymlinkTests.test_directory_link.

Overall, I agree that this doesn't work correctly. The patch, which is pretty large, breaks more than it fixes.

I'll see if I can make time during the day tomorrow to look further into the code, and I'll try to coordinate with Jason if possible.
