That's almost identical to what the current os.path.sameopenfile is.

Lib/ntpath.py opens both files, then compares them via _getfileinformation.
That function is implemented to take in a file descriptor, call
GetFileInformationByHandle with it, then returns a tuple
of dwVolumeSerialNumber, nFileIndexHigh, and nFileIndexLow.
