Private
MessagePort.postMessage(message: any,transfer: Transferable[],): void 
      Posts a message through the channel. Objects listed in transfer are
transferred, not just cloned, meaning that they are no longer usable on the
sending side.
Throws a "DataCloneError" DOMException if transfer contains duplicate
objects or port, or if message could not be cloned.
