The thing to keep in mind is that a pipeline is not a unit of execution,  
it is a unit
of configuration.   CPF runs in an asynchronous event-based fashion, and so
what really matters is the set of rules for a particular state.  Only one  
action will
be executed for any given state, so if you want to do one thing and then  
another
thing, have state1 execute thing1 and set the state to state2, and have  
state2
execute thing2.
