• background processes
• task complete/not complete state can be stored, used to present spinning wheel or something
• could be used to block/queue ingests if one is already running from another user

The feedback portion is being implemented by e.g. a53c8ae.

The background tasks portion is going to have to wait. That is waay complex.
