   * {@link java.lang.Error} sublcass that indicates a lua thread that is no
   * longer referenced has been detected.
   * <p>
   * The java thread in which this is thrown should correspond to a
   * {@link LuaThread} being used as a coroutine that could not possibly be
   * resumed again because there are no more references to the LuaThread with
   * which it is associated. Rather than locking up resources forever, this error
   * is thrown, and should fall through all the way to the thread's {@link Thread.run}() method.
   * <p>
   * Java code mixed with the luaj vm should not catch this error because it may
   * occur when the coroutine is not running, so any processing done during error
   * handling could break the thread-safety of the application because other lua
   * processing could be going on in a different thread.
