> When invoking RPCs, {{RpcDispatcher}} converts the {{MethodCall}} used into a byte array and passes that to a {{BytesMessage}} that's then sent down to the transport.
> This is inefficient, as an unneeded byte array allocation is done, both when an RPC request is sent and when the response is sent.
> Instead of doing eager marshalling of {{MethodCall}} into a byte array, pass the {{MethodCall}} to an {{ObjectMessage}}, which marshalls the latter directly to the output stream of the transport at send time.
> This eliminates 2 memory allocations per RPC round-trip (on a sync RPC).
