PR which addresses an intermittent bug in the
SimpleJobRunner
class, when trying to access info on a job which has been removed.It's unclear what triggers the bug but I'm speculating that it's due to a race condition when the class is used in a threaded context (for example, within the
simple_scheduler
module from theauto_process_ngs
package).
