277 Basically, heres what this should do:
278 1) Determine correct packet handler for this packet
279 2) Mark the packet handled (so it can be dequeued in purge_queue())
280 3) Send the packet to the packet handler
281 4) Go to next packet in the queue and start over
282 5) When done, run purge_queue() to purge handled commands
283
284 Note that any unhandlable packets should probably be left in the
285 queue. This is the best way to prevent data loss. This means
286 that a single packet may get looked at by this function multiple
287 times. This is more good than bad! This behavior may change.
288
289 Aren't queue's fun?
