I had hope this was resolved in the new version but it appears it’s still
possible with consolidate jobs that you can hang the system.
Short SD never actually lets a volume swap to a second job. This happens when
you have multiple concurrent jobs allowed. I would be ok serilizing virtual
jobs but that appears not possible if you want to allow parallel real jobs.

This just goes on forever until you restart the SD which will cause the job to
fail rather than wait on mount, and the next time it will run fine if it is
able to grab the volume that’s needed first.
Expected behavior is that once the job that first reserved the volume finishes
it is released for the other job that’s waiting.
