Title: Ensure jobtemp spill files are replicated

There can be a large period of time between thor executing different
graphs in a workunit, e.g., if other high priority jobs take precedence.
This means it is more likely that a machine may have been swapped in
the meantime. Therefore any file which has lifetime beyond a single
graph should be replicated - otherwise the entire job may need to be
rerun.

Fixes #1944.
