/** Test for Bug 646641 **/
/**
* Steps:
* - Main page (this one) opens file_bfcache_plus_hash_1.html (subpage 1)
* - subpage 1 sends msg { "childLoad", 1 }
* - subpage 1 sends msg { "childPageshow", 1 }
* - main page sends message "pushState"
* - subpage 1 does pushState()
* - subpage 1 navigates to file_bfcache_plus_hash_2.html (subpage 2)
* - subpage 2 sends msg { "childLoad", 2 }
* - subpage 2 sends msg { "childPageshow", 2 }
* - main page sends msg "go-2"
* - subpage 2 goes back two history entries
* - subpage 1 sends msg { "childPageshow", 1 }
* - Receiving only this msg shows we have retrieved the document from bfcache
* - main page sends msg "close"
* - subpage 1 sends msg "closed"
