> The inclusion of controller configuration files can lead to inclusion cycles 
> which are not safely handled, because they can lead to infinite recursion 
> that end up in stack overflow exception.
> A very basic form of cycle is controllers A and B which includes each other.
> I would be better to check the inclusion cycles and report an appropriate 
> error.
