Just thinking loud.  I was initially wondering the purpose of this link.  Seems
this was added to show the example of pagemap.h touching patch that can
dmonstrate how many CC can be reduced.  I once thought about suggesting to add
the number or the context on the description, but realize it is too trivial.
So just thinking loud.
