// async task, so we have no way to guarantee the order in which their bytes will be read, and
// it doesn't really matter in this context. We just want to see that the layout is initially
// created properly and that in the end it's populated properly with its content
//
// we read the next to last as well as the last, because the last includes the "Bye from
// Mosaic" message, and we also want to make sure things are fine before that
