Yup, you got it.  Using a null "existing handle" argument gets a local
top-level handle.  If you think how this can be implemented (handle is
a kernel data pointer), then consider how the kernel implementation of
"pathname" parsing for obj_open (which I think of as "subopen") can
take advantage of the uniformity, you'll see some of the other potential
advantages.  This seems to nicely accommodate portals, remote object
access, and so forth.
