FWIW, CVS cygwin had a similar bug for about a one month window a while
ago: http://cygwin.com/ml/cygwin/2007-09/msg00407.html
I found it very annoying when using cygwin snapshots where mv would fail
but cp succeed, all because open was creating the file while returning -1.
Fortunately, current cygwin snapshots no longer have this bug.

Agreed. I would push back on the CIFS people to fix their bug.
