Description

In order to avoid missing close() calls on file descriptors, or double-closing file descriptors, it would be nice to add a reference counted FileDescriptor in a similar way to what we've done for Socket. This will be closed automatically when the last reference goes away, and double closes can be prevented via internal state.
