You might be working on something slightly different, but I have an issue
created for the failure of that test: http://bugs.python.org/issue10540

It slipped past me because I was only running the test suite as a regular
user without the required symlink privilege, so the test was skipped. That
Server 2008 build slave runs the test suite as administrator, so it was
running that test and going into the os.link block, which it didn't do until
r86733.
