--------------------------------------------------

This sounds related to some of the work [~sseth] was doing at HADOOP-11552.

> In ipc.Client, the underlying mechanism is already supporting asynchronous calls -- the calls shares a connection, the call requests are sent using a thread pool and the responses can be out of order.  Indeed, synchronized call is implemented by invoking wait() in the caller thread in order to wait for the server response.
> In this JIRA, we change ipc.Client to support asynchronous mode.  In asynchronous mode, it return once the request has been sent out but not wait for the response from the server.
