        I implemented this an did some performance benchmarks.
        It did help initial block report processing and eliminated duplicated block-reports due to timeout.
        However, when I combined this with the random backoff (hadoop-2326) it did not help.

        Furthermore, once we cleaniup the RPC layer to remove the client-side timeouts and retries, this work will be obsolete and there
        does not seem to be a good reason to have a dedicated queue and thread for the block report rpc.
