Brain.Queue.IsFull() == true

Lead: Hey, do we have two queues for sent and received messages?

Me: No, we only have one for sent messages. Because of the hardware, we can only receive one message a time.

Lead: So we have 2 queues?

Me: No, just one. For sending.

Lead: So wait a second... what do we do for receiving?

Me: We receive a packet and process it and then it goes away?

Lead: What about sending?

Me: There's a queue.

Lead: So... we DO have 2 queues?
