The `-reschedule` flag stops allocations and assumes the Nomad scheduler will create new allocations to replace them. But this is only true for service and batch jobs. Restarting non-service jobs with the `-reschedule` flag causes the command to loop forever waiting for the allocations to be replaced, which never happens. Allocations for system jobs may be replaced by triggering an evaluation after each stop to cause the reconciler to run again. Sysbatch jobs should not be allowed to be rescheduled as they are never replaced by the scheduler.
