Subject: *Semantic change*: when unpickling the instance variables of an
 instance, use inst.__dict__.update(value) instead of a for loop with
 setattr() over the value.keys().  This is more consistent (the pickling
 doesn't use getattr() either but pickles inst.__dict__) and avoids problems
 with instances that have a __setattr__ hook.

But it *is* a semantic change (because the setattr hook is no longer
used).  So beware!
