pickle question: sequencing of operations

[Russell E. Owen]

What is the sequence of calls when unpickling a class with __setstate__?

>From experimentation I see that __setstate__ is called and __init__ is 
not, but I think I need more info.

I'm trying to pickle an instance of a class that is a subclass of 
another class that contains unpickleable objects.

What I'd like to do is basically just pickle the constructor parameters 
and then use those to reconstruct the object on unpickle, but I'm not 
sure how to go about this. Or an example if anyone has one.
