Here's one way it could go:

User was at http://google.com, types http://mozilla.com/index.html#1
into address bar.
* onload
* stateactivated
User clicks on link with href "#2"
* statedeactivated (until this event is complete,
document.location.hash == "#1" and the pageStorage object is for the
"#1" state)
* stateactivated (at the beginning of this event,
document.location.hash == "#2" and the pageStorage object is for the
"#2" state)
User clicks back
* statedeactivated (for #2)
* stateactivated (for #1)

I might be introducing horrible races into the HTML5 event model by
doing this, though.
