* This testcase does the following steps to make sure that bug767025 removes

*
* STEPS:
* - Schedule a offline cache update for app.manifest.
* - pages/foo1, pages/foo2, pages/foo3, and pages/foo4 are cached.
* - Activate pages/foo1
* - Doom pages/foo1, and pages/foo2.
* - pages/foo1 should keep alive while pages/foo2 was gone.
* - Activate pages/foo3
* - Evict all documents.
* - all documents except pages/foo1 are gone since pages/foo1 & pages/foo3
* are activated.
