Issue 30: Reduce context fanout during packing / unpacking
Project Member Reported by kevin.bi...@gmail.com, Sep 23, 2008
Packing tries all possible states, which creates a large number of
contexts, many of which are possible if not many state invariants are
present.  This seems to be affecting performance. 

Could just pack to the root state and wrangle later where needed, or
something like that.
