It's using a hash table rather than a tree set, so I don't think the additional memory will be a problem - there are only about 10,000 txs or so right now, so I don't think it will take up more than 100KB or so. (The fact that DaoState.blocks is a linked list instead of an array list is probably a more significant memory issue that could be easily fixed.)
