 This requirement is aimed at enabling process migration and job control as well
 as post-hoc analysis of experiment results.
 
+OD asks: When you say "The experiment cannot assume that resources written by
+the experiment will still be there", do you mean we should be able to recover
+the exact same output after interrupting an experiment, wiping its expdir, and
+restarting it? 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.
