On Windows, the "default" is not shared in the sense that that is what you get if you pass no specific sharing parameters (0). I'm not windows expert, but if I read the CreateFile docs correctly, having some form of sharing as default can be wrong (causing errors) in some cases?

On Posix, the situation is quite different in that sharing is default. In fact non-sharing is not enforced by the system such that it is up to the application to figure out whether it should stay away or not. 

I believe there is room for improvement, but I'm not sure the default should be different?
