I have a use case where I'd like to uniquely identify a network namespace given a netns handle. The netns handle itself does this job but also keeps the associated file handle open. The proposed function UniqueId returns a string identifier which uniquely identifies the network namespace (using the inode and dev keys similar to the Equal comparison function). The caller can then choose to close the handle and still hold on to the unique string identifier.
