> alternate functions through a single handle with additional and somewhat scary methods like ioctl. Plan9 manages this with servers, directories, and more than one path available for a single resource depending on what you're trying to access. This is far more sane. Given how horribly asynchronous filesystems are I take one handle owned by the current process over a dozen free hanging files that might be reused for different resources at any time. Hell I am quite sure Linux had to kill suid on scripts because the kernel could not guarantee that the script file wasn't swapped out before the interpreter would load the path.
