I think you need to reread the specs, I see one very important case
where your proposal fails, consider the following:  a program calls
shmget with key = IPC_PRIVATE.  shmget returns the id.  The program now
communicates this id to its children and they attempt to shmat it, yet,
because this refers to a file descriptor, they fail.
