OT: POSIX named semaphores?

I realize this is probably off topic, but I figured I would ask anyway:
in NGPT 1.9.2, I find in semaphore.c:

sem_t *__sem_open(const char *name, int oflag, ...)
{
    return_errno(SEM_FAILED, ENOSYS);
}

Since process-shared semaphores are now supported in sem_init(), what
about POSIX named semaphores? Would it be possible to implement that
in the context of NGPT, or are there missing kernel services which
make this difficult/impossible?

Thanks,
JF
