Uses a store to implement the page pool interface MPagePool.

Pages can be reclaimable (tracked by the page pool, so that they can be freed when required) or not (in which case they must be deleted explicitly): this is indicated by a flag of type TPageReclamation. Non-reclaimable pages each have their own stream in the store; reclaimable pages are bundled 15 to a stream. To track the reclaimable pages, the page pool has a separate token, type TStorePagePoolToken, that must be saved by the user of the pool.

The store used must support CStreamStore::ExtendL(), CStreamStore::DeleteL() and allow streams to be re-written. CPermanentFileStore meets these conditions.

A store page pool uses a cache to store pages in-memory and to cache frequently accessed pages. You should provide a cache object (CPageCache) to the pool for this purpose.
