After using this library in production for a while I have found that the current approach of keeping track of failed tasks in a
setin memory doesn't work in a satisfactory way. I have multiple workers running jobs from the same queue. Every worker will pick up jobs that are bound to fail. Then, on a restart (i.e. deploy) thesetis destroyed and the jobs are up for grabs again. So I thought... why not keep that state in the database on theJobobjects themselves?
