Review comment:
Thanks for the pointer to `priorExecutions`. I missed it out completely.
You're saying that instead of caching the `Throwable`s in
`SchedulerBase::executionCache` I should use `Execution::priorExecution`?! That
makes sense as we avoid saving the same information twice. But I would have to
change the `priorCause` to `ErrorInfo` (instead of `Throwable`) to also collect
the time when the `Throwable` was caught. Am I right?
