*
* - Request nsOfflineCacheService to skip pages (4) of app1 on

*
* - The offline cache storage is empty at this monent.
*
* - start_cache_nonpinned_app2_for_partial()
*
* - Request nsOfflineCacheService to skip pages of app2 on the
* cache storage.
*
* - The offline cache storage has only enough space for one more
* additional page. Only first of pages is really in the cache.
*
* - start_cache_pinned_app2_for_success()
*
* - Request nsOfflineCacheService to skip pages of app2 on the
* cache storage.
*
* - The offline cache storage has only enough space for one
* additional page. But, this is a pinned request,
* nsOfflineCacheService will make more space for this request
* by discarding app1 (non-pinned)
