By the way, a colleague of mine who was bothered by
this problem (MFC Cfile objects leaking parent dir handles)
found out that this problem only started with "MFC42.dll" in
Version 6.6, which is installed in both "System32" and in
"SysWoW64" subdirs of an XP/x64. He tried to replace it
with the version 6.2, which is usually part of XP/ia32,
but every time he deletes it or overwrites it, when he reboots
the version 6.6 is again there.

In short - by putting the "MFC42.dll" version 6.2 in the
same directory with the executable, e.g. "Tester.exe",
the problem can also be solved but your patch is a much
cleaner solution, especially knowing that it is part of the
new Samba 3.0.28a.

Thank you very much.
