/* Windows does obviously not update the stat info during a write call. I
* *think* this is the problem causing a spurious Excel 2003 on XP error
* message when saving a file. Excel does a setfileinfo, writes, and then does
* a getpath(!)info. Or so... For Samba sometimes it displays an error message
* that the file might have been changed in between. What i've been able to
* trace down is that this happens if the getpathinfo after the write shows a
* different last write time than the setfileinfo showed. This is really
* nasty....
