Maja Kabiljo updated GIRAPH-297:
--------------------------------
Attachment: GIRAPH-297-fix.patch
This patch introduced a bug: with finalizing checkpoint I also moved the old
superstep cleanup - my logic was that it's fine because of the new barrier. But
barrier only happens in supersteps in which we do checkpointing. I am returning
cleanup to its previous place. Unfortunately the bug was not discovered by any
of our tests, since cleanup happens before it should only with one specific
order of events.
> Checkpointing on master is done one superstep later
