Use a LocalSocket to represent the connection between two message ports. The concept of the port message queue is still missing, however. When that concept is implemented, the "steps" in step 7 of the message port transfer steps will need to send the serialized data over the connected socketpair and run in the event loop of the process that holds onto the other side of the message port. Doing this should allow centralizing the behavior of postMessage for Window, MessagePorts and Workers.
