One corner case I think we've seen which could lead to confusion is
that once a job enters the Gearman queue it doesn't get removed even
if Zuul removes it from the pipeline... so if your worker volume is
backed up enough that some jobs for a patchset haven't been assigned
before another patchset causes the current one to get dequeued,
Jenkins can end up running those jobs anyway.

Did we ever end up implementing a solution for that, or does that
behavior still exist?
