I think you probably are correct. The only thing I can think that might 
help is if you can catch all the situations where changes to the dependent 
values might change the hash and wrap them up: before changing the hash pop 
the item out of the dict, then reinsert it after the change.

Alternatively give up on defining hash and __eq__ for FragmentInfo and rely 
on object identity instead.
