If this method is called inside a callback, we are already inside a Fiber handler. In that case, we write to the stream and yield the Fiber. Once the response is received, resume the Fiber and return the result.

If this method is called outside a callback, write to the stream and run the event loop until a response is received. Messages received in the meantime are enqueued to be handled later.

Run the event loop, handling messages in a Fiber.
