This would mean that any output saved on disk by the experiment +also has to be serialized within the experiment, which may lead to very big +serialization files (and possibly memory issues?) +A less constraining interpretation of your statement (which I like better) is +that we allow "previous" output to be lost: we only ask that the experiment +should be able to produce the "new" outputs after a wipe+restart.
