What's needed even more is optional per/segment page tables.
i.e. a separate page table for each segment when so desired. This
would overcome the current 486 limitation that any accessible segment
must be completely mapped into one 32-bit virtual address space.
The implication of this limitation is that, if you want to address
6 or more segments simultaneously, no segment can be greater than
1/8th of the address space (=512megabytes).
