With a variable-based restart mechanism, I think it will remember that the 
variable has been closed. With filename-based restarts, I think no.

Perhaps restarting might bring up the same kind of problems as replication 
and retries - if some data processing got half-way through and then 
abandoned/broken/whatever, the various things Swift does to make 
application execution appear atomic wrt application output files won't 
happen here.
