 * This class ensures that at most one thread is running at a time. This is initially the JUnit test
 * thread, which yields its execution privilege while calling [runTasks], [runNextTask], or

 * Commands are received on communication threads and then processed sequentially on the main thread.  Although concurrent calls to
 * any of the methods from {@link RemoteTestClassProcessor} are supported, the commands will still be executed sequentially in the
 * main thread in order of arrival.
