We clear out claim queues at the end of the session. This leads to nodes not seeing anything scheduled for the next block. This is fixed by explicitly updating the claim queues in the availability_cores runtime API.

This ended up including a few further fixes and cleanups. Code is still not clean, but cleaner.

Simplification that fell out from changing the type of scheduled.

Don't duplicate time out logic, but use same function as the scheduler uses to avoid this to diverge from reality.

No longer true. Only worked with the None hack.
