Old description:

> When a commflag job fails (segfaults) it leaves an active entry in the
> job queue. When the number of active but failed commflag entries in the
> job queue equal the maximum simultaneous jobs allowed by the user, future
> commflag jobs are not run.  After manually deleting the entries for the
> failed jobs from the job queue, queued commflag jobs start running.
>
> Trunk version 26977

New description:

 MythWeb has no protection insertion of new jobs into the jobqueue table.
 If two instances of the details page are opened and the same job run
 twice, or the user hits the back button triggering a repeat submission, a
 duplicate job can be added to the table. This results in the second copy
 of the job being left in the queue indefinitely, confusing subsequent host
 selection of tasks.

 This will be rendered a non-issue by the jobqueue rewrite, if not fixed by
 the time that gets merged in.
