In the order you asked: it sounds as if he has already bought a system,
now all he needs is Xenix/386 and more memory. Virtual address space is
a function of the swap size and physical memory. A high ratio of logical
to physical memory in a program will usually result in poor performance.
The memory is managed by the o/s, language doesn't matter.
