method MessagePort.prototype.start
Jump to headingMessagePort.prototype.start(): voidStarts receiving messages on this MessagePort. When using this port
as an event emitter, this is called automatically once 'message' listeners are attached.
This method exists for parity with the Web MessagePort API. In Node.js,
it is only useful for ignoring messages when no event listener is present.
Node.js also diverges in its handling of .onmessage. Setting it
automatically calls .start(), but unsetting it lets messages queue up
until a new handler is set or the port is discarded.
