Summary: os.stat() WindowsError 13 when file in use

Initial Comment:
Using 2.5 Sept 19, 2006 on Windows XP, 32-bit.

os.stat() on an "in use" file (i.e., open by another process) erroneously returns WindowsError [Error 13]. The file stats should be available on an open file, even if you cannot read/write the file itself.

Python 2.4 correctly returns the stats on the file.

----------------
CORRECT in 2.4:
Python 2.4.4 (#71, Oct 18 2006, 08:34:43) [MSC v.1310 32 bit (Intel)] on win32
>>> import os
>>> os.stat('c:\\hiberfil.sys')
(33206, 0L, 2, 1, 0, 0, 804311040L, 1173962381, 1173962381, 1069302780)

-----------------
ERROR in 2.5:
Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win32
>>> import os
>>> os.stat("c:\\hiberfil.sys")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
WindowsError: [Error 13] The process cannot access the file because it is being
used by another process: 'c:\\hiberfil.sys'
