Comment (by rhaas):

 Is this discussion still useful? Given that we are still waiting for HDF5
 journalling support, right now the only viable option is to checkpoint
 only at terminate (for regular sized runs) and for those runs that are big
 enough to expect node failures while they are running, write checkpoints
 multiple times per simfactory segement to pray that corruption does not
 happen while one has the output file open (so that one does not lose the
 whole segment).

 Basically: since we are actively promoting simfactory which mitigates the
 problem we are no longer on the hook for fixing hdf5's problems.
