OS/161 Reference Kernel:
* Sequential TLB replacement
* 512 kB RAM in machine configuration
* 74 pages physical memory managed by coremap

Below are the raw numbers reported by the "vm" menu command when running
each the matmult and sort programs with random and clock page replacement.
The kernel was re-booted before each test.

Random page replacement
-----------------------

testbin/matmult:
vm: 383 zerofills 432 minorfaults 431 majorfaults
vm: 751 evictions (358 discarding, 393 writes)

testbin/sort:
vm: 292 zerofills 862 minorfaults 1669 majorfaults
vm: 1898 evictions (689 discarding, 1209 writes)

Clock page replacement (LRU approximation):
-------------------------------------------

testbin/matmult:
vm: 383 zerofills 445 minorfaults 383 majorfaults
vm: 703 evictions (316 discarding, 387 writes)

testbin/sort:
vm: 292 zerofills 544 minorfaults 1628 majorfaults
vm: 1857 evictions (654 discarding, 1203 writes)
