We need to think about a new better permissions api for the System.Directory module. The current api and also the implementation are at best useless and possibly harmful.

Perhaps there's something we can learn from the rearchitecture of Java's file handling that's happening in NIO 2. They're overhauling how files, directories, file systems, links, and metadata is handled. They address things such as providing both a lowest common denominator layer and platform specific "extensions".

See for example http://javanio.info/filearea/nioserver/WhatsNewNIO2.pdf starting at slide 17.

Yes, I'm sure there are some good ideas to consider there. I looked at NIO1 and it's got some fairly sensible stuff. Duncan
