> If RPC server is asked to stop when RPCCallQueue is full, {{reader.join()}}
> will just wait there. That is because
> 1. The reader thread is blocked on {{callQueue.put(call);}}.
> 2. When RPC server is asked to stop, it will interrupt all handler threads
> and thus no threads will drain the callQueue.
