if you read my (radical) proposal, the identification is based on a kernel pointer and a 256-bit random integer. So non-negative integers are not needed. (file-IO system-calls would be modified to detect if 'Unix file descriptors' or pointers to 'native file descriptors' are passed to them, so this is truly radical.)
