    Description

      Currently, if you disable TCP_NODELAY in the IPC client, you get an extra packet for each call which contains the call's length. This is unnecessary. Instead, we can just reserve the 4 bytes in the buffer up front, then go back to fill it in before pushing the call to the wire.
