Ok, so save time at the end of the callback, and compare at the start
of the callback.  If > 10 seconds, clear our throttle buffer!

^ Ok, here's the problem:  Pacer.  We get a message, login, process.
Then what?  The problem is, we want to logout after 4-5 seconds of 
nothing to do.

Replacing:
channel.start_consuming()
with
while channel._consumer_infos:
  channel.connection.process_data_events(time_time=1)
  print("Ok!  I can do something between events / when I have no events.")

See worker2.py for working example of this.

^ This allows us to do something (like see if we are logged in, and if a certain amount of time
has passed or not.  We'll be able to logout / do other things.

I'm not sure about the 1 second.  I don't need it to be like that.  Maybe 60?  (Every minute?)  or

if we're waiting for work, set at 10, if we're logged out, set to 60.
