	Hi Yukio

We think that you should take a look how the queue.cc and delay.cc work together. When you receive a packet, check if you are already processing a packet (block flag or something). If not blocked, block object and process packet, if blocked, put packet in queue for later processing.

When packet processed, release the object with a callback function.

This is just what Queue and LinkDelay does; all you have to do is to spawn new packets.

Hope this cleared some of your problems.
