I'm not sure I understand what you mean regarding using the "include"
element (i.e., precisely what you're doing) but I thought that each package
would have its own set of interceptors, meaning there would be two
instances, hence init would be called twice.
This would be trivial to determine by checking to see if it's the same
instance.
I could be misremembering.
