Hmm, no, I haven't considered that. You mean that a bgworker that
specifies to start at BgWorkerStart_ConsistentState will stop once
normal mode is reached? Currently they don't do that. And since we
don't have the notion that workers stop working, it wouldn't work --
postmaster would start them back up immediately.
