> With EOS enabled we don't checkpoint on {{commit}} so there is no need to 
> call {{flush}} when committing _top level tasks_ .  However for _standby 
> tasks_ we still checkpoint thus need to still flush when committing. We need 
> to develop an approach where we can optimize for top level tasks by avoid 
> flushing on commit, while still preserving flush on commit for standby tasks.
