The database thread loop looks like this:

    while (!m_terminationRequested) {
        m_threadMutex.unlock();
        AutodrainedPool pool;

        LOG(StorageAPI, "Iteration of main loop for DatabaseThread %p", this);

        bool result;
        do {
            result = dispatchNextTaskIdentifier();
            if (m_terminationRequested)
                break;
        } while(result);

        if (m_terminationRequested)
            break;

        pool.cycle();
        m_threadMutex.lock();
        m_threadCondition.wait(m_threadMutex);
    }

It's pretty clear how the wakeup is lost - if a new task is dispatched after
the inner loop has decided that it has nothing else to do, but before we're
stopped on the condition, the condition is signaled in vain.
