>
> doing the fetch in the EventHandler has the drawback of tying up the
> EventHandling thread, in case it takes time to read the Index file. Even, for
> a healthy disk - we can do without any delays on this thread, so that the
> fetcher have some work to do.
> Also Need to add Unit test cases for the local fetch.
