--- Comment #2 from Yusuke Suzuki <ysuzuki at apple.com> ---
Currently, MessagePort postMessage w/ WebAssembly.Module is not supported.

We need to know the notion of the followings.

1. This pair of MessagePorts are in the same process so that we can send SerializedScriptValue without using IPC back-and-force
2. This pair of MessagePorts are in the different process so that we should just throw an onmessageerror exception.

Chris, do you know about MessagePort's remote/not-remote flags? Is it specified?
