           Summary: [DumpRenderTree] IndexedDB: Each page group/worker has
                    a distinct IDBFactoryBackend
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org

The PageGroupIndexedDatabase and WorkerContextIndexedDatabase classes contain IDBFactoryBackendInterface members which are initialized lazily. The IndexedDB implementation assumes there is a single IDBFactoryBackendImpl instance for the entire browser, since it controls access to the backing store, maintains open database connections, and schedules transactions.

The result is that a page and worker, or two workers, that attempt to open connections to the same database end up talking to completely distinct database instances.
