In KeyKOS, a segment can be larger than the size of an address space,
and a domain root can point to such a segment (though there's little
reason to do so). I'm not sure if this is allowed in EROS/CapROS. The
first node with SSC/BLSS less than or equal to 6 (corresponding to
2^32) defines the whole address space.
