> We need to re-examine the startup procedure of the scheduler, and how it interacts with the startup of the operator coordinators.
> We need to make sure the following conditions are met:
>   - The Operator Coordinators are started before the first action happens that they need to be informed of. That includes as task being ready, a checkpoint happening, etc.
>   - The scheduler must be started to the point that it can handle "failGlobal()" calls, because the coordinators might trigger that during their startup when an exception in "start()" occurs.
