Where is os.stat() defined in CPython?
===

I've looked through the CPython sources ([Hg online here][1]), but I can't seem to find where `os.stat()` is defined. It looks like `stat` is magically a global in the `os` module (Lib/os.py, ca. line 139).

Can someone point me to the appropriate file(s)?
