Looking at this from another angle: If any Runnable that is scheduled ever
lets an exception bubble out, can we still assume that the JobManager is in a
sane state? Or should be actually make every uncaught exception in the RPC
executors a fatal error and send a `notifyFatalError` to the `RpcEndpoint`?
