An interesting thing I discovered is that Windows simply ignores the 'x' bit (I should say the Windows equivalent of the 'x' bit, called "traverse folder / execute file"), but there is a policy setting that overrides this attribute.

I know users get tripped up on this a lot in Unix, like when they don't understand why the webserver can't read their public_html directory. It might be a good option for Linux.

The right solution is to have a separate readdir permission, so that a file-directory can be not executable but be listable, and vice-versa. The problem comes from overloading the bit and also changing whether objects can be simultaneously files and directories.
