Hi,

I read the docs about lockfree::queue::empty() and understang what this way
is not safe in multithreaded program.
The question is, how can I verify that the queue is empty?
Will it be correct the following code?

bool empty() {
   T *tmp = 0;
   if ( queue.pop(tmp) ) {
      queue.push(tmp);
      return false;
   }
   return true;
}

Thanks.
