So what happens with that football thing -- you're saying thread
spawning issues, so kthread_create() is not making progress?

You're also saying 'keeping the dl_server running for the whole period',
are you seeing it not being limited to its allocated bandwidth?

Per the bug today, the dl_server does get throttled, not sufficiently?
