I see, so I guess we need to distinguish between windows under cygwin
and a normal windows file system?  I suppose this needs another
option, although Greg Freemyer posted some code to recognize vfat
systems mounted under linux in some circumstances.  How does cygwin
store ownership information?

The problem here seems to be that a directory cannot be fsync'd.
Perhaps your file system does not allow that operation?  Under linux
it is required to guarantee that a file has been added to a
directory.

When I mount a vfat file system under linux, fsync does work:

Python 2.2.1 (#1, Aug 30 2002, 12:15:30) 
[GCC 3.2 20020822 (Red Hat Linux Rawhide 3.2-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> fp = open("/mnt/fat/temp", "rb")
>>> os.fsync(fp.fileno())
>>> 

Does this fail for you?
