 /**
  * A special class which works exactly like KisSignalCompressor, but
  * supports calling \p start() method from within the context of
  * another thread. If it happens, it posts a message to Qt's event
  * loop and the \p start() signal is delivered when event loop gets
  * executes again.
  *
  * WARNING: After creation this object moves itself into the main
  *          thread, so one must *not* delete it explicitly. Use
  *          deleteLater() instead. Moving into another thread is
  *          another reason why it cannot have parent QObject.
