[PageVisibility] Need to define interaction with page navigation

In particular, does visibility state change when documents are unloaded? 
  What if they're going into the history cache or coming out of it? 
Does the visibility change notification fire in that case, and if so, 
how is it ordered with pageshow and pagehide?
