示例1: try_timed_wait_for_data
/// Returns immediately of queue size is >= immedeiate_size
/// Otherwise, it will poll over 'ns' nanoseconds or on a signal
/// until queue is not empty.

m_mutex.lock();
bool success = false;
// Wait while the queue is empty and this queue is alive
if (m_queue.size() < immediate_size) {
if (m_queue.empty() && m_alive) {
