It is used automatically on platforms supporting the necessary os.openat() and os.unlinkat() functions. Main code by Martin von Löwis.
Unfortunately, this isn't actually having any effect at the moment since the os module APIs changed for the beta release.
The "hasattr(os, 'unlinkat')" and "hasattr(os, 'openat')" checks need to become "os.unlink in os.supports_dir_fd" and "os.open in os.supports_dir_fd", and the affected calls need to be updated to pass "dir_fd" as an argument to the normal versions of the functions.
At least we know the graceful fallback to the old behaviour is indeed graceful, though :)
Yeah I've been told on IRC already. I'll commit a fix in a few minutes if my regression tests on OS X and Linux work fine.
