It wouldn't run DOS. There would be a Linux kernel running a full-blown workload manager ... which is severely misconfigured.
- Tasks are waiting in the queue for months (sometimes years).
- Some tasks are running for very long and then get terminated in favor to a new task which got enqueued a second ago.
- Most tasks crash (segfault), due to overallocated memory.
- CPU load is constantly at 100% although many tasks are just idling.
At least that's the case in ADHD brains.
