           Summary: [BlackBerry] Clear local storage won't take effect
                    until browser exit and relaunch
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2

RIM PR: #146871

way to reproduce:
1. goto http://html5demos.com/storage, enter something both in session storage
and local storage, then reload the page, you can see the session and local
storage are there;
2. clear local storage;
3. refresh the page.

expected behavior:
session storage still there, local storage is empty;
now:
session storage and local storage are still there both. if you exit and
relaunch the browser, the local storage is cleared.


root cause:
in WebPageClientImpl::clearLocalStorage(), we only deleted the storage database
file on disk, but we haven't cleared the local storage in memory.
