Without knowing more it's hard to say, but my guess is that you are doing
something that takes long in the setup method of the agents that get
created, or in the contructors of the behaviours that your are adding.
Make sure that the setup method returns quickly and make sure you don't do
synchronous operations either in the constructor of the agents, or in the
constructors of the behaviours you are adding in the setup method.
If you need "initialization" synchronous operations in the behaviours, use
onStart() or in the start() with a flag..not the constructor of the
I'm also learning jade and I found myself doing that very often - not
