284 Basically, heres what this should do:
285 1) Determine correct packet handler for this packet
286 2) Mark the packet handled (so it can be dequeued in purge_queue())
287 3) Send the packet to the packet handler
288 4) Go to next packet in the queue and start over
289 5) When done, run purge_queue() to purge handled commands
290
291 Note that any unhandlable packets should probably be left in the
292 queue. This is the best way to prevent data loss. This means
293 that a single packet may get looked at by this function multiple
294 times. This is more good than bad! This behavior may change.
295
296 Aren't queue's fun?
