------------------------------------
Hi [~srichter]
IIUC, only subtasks that are assigned to the original physical machine can use
the local state.
For a subtask, will part of its state come from the local state and part from
the remote state? Does this require the scheduler to do anything else?

> Local state is currently only used for recovery. However, it would make sense
