This will fail hard when users rely on the result of the first job. So
imagine your program always worked. You submit it detached and then it fails
after 12 hours when the first job completes. Granted, we could alleviate the
problem a bit by only allowing execute() for detached programs because then the
date has been written to a proper sink. Still, the accumulator values might be
used after job completion.
