> Now we just assert that last saved tag in tracking page should be not greater than passed
> But because of different issues which we don't understand yet, it could happen.
> So, I suggest to handle it by adding new "corruption" state to tracking state. 
> If tracking page is in a corrupted state than we would throw an exception on any querying
of the tracking page. Caller will have opportunity to catch the exception and recover page
