If 97% of page table accesses take 100ns and 3% take 3us, then the AVERAGE
page table access takes .97*.1us + .03*3us = 187ns.  This is still speedy
virtual address to physical address translation for a micro.  By comparison
the Z8010 MMU at 10MHz takes 250ns to do the translation, and does not have
the nice features that the 16032 MMU has (like reference bits or cache).
