-/**
- * TODO: Replace the PendingThreadMaintainer by a kind of
- *       VersionControlThreadFactory that is responsible for creating
- *       and deleting the threads. This would bypass the hack to poll
- *       for pending threads.
- *
- * If the creator of a thread gets deleted, although the thread is still
- * working, usually QThread::wait() is invoked. The drawback of this
- * approach is that the user interface gets blocked for an undefined amount
- * of time. If the thread does not contain references to the creator, the
- * deleting can be forwarded to the PendingThreadsMaintainer. In the following
- * example it is assumed, that m_thread will be 0, if it has been deleted by the
- * creator after receiving the signal QThread::finished():
- *
- * \code
- * ThreadCreator::~ThreadCreator()
- * {
- *     if (m_thread) {
- *         PendingThreadsMaintainer::instance().append(m_thread);
- *         m_thread = 0;
- *     }
- * }
- * \endcode
- *
- * The thread will get automatically deleted after it (or has already) been finished.
- *
- * Implementation note: Connecting to the signal QThread::finished() is
- * not sufficient, as it is possible that the thread has already emitted
- * the signal, but the signal has not been received yet by the thread creator.
- * Because of this a polling is done each 5 seconds to check, whether the
- * thread has been finished.
