Bug Description
When using objects containing mutable variables (Pickle, List) these objects don't detect changes if the object is in the alive list after a commit.
The attached file demonstrates this behavior. In line 88 I do a commit which doesn't update the object in the database.
The problem is that the variable for the pickle is not checkpointed if the object comes from the alive cache and is read using store.find(). If store.get() is used it works fine.
The mutable variable needs to be checkpointed in order to emit a "changed" event.
