The Control Data Cyber 180 line follows the Multics model fairly closely. Each process may have 4095 segments of length 2**32. The segments may be shared by multiple processes. I/O is actually paged memory accesses. I don't know much about the hardware, but I don't think the segment validation causes that much of an overhead problem.
