I'm aware of what can cause a post to exit a review queue. This question is about what can cause a post to return to a queue that it's already been through.
I know that a post only goes through the First Posts or Late Answers queue once; reviewing those more than once would be kind of silly. And I know that any given suggested edit goes through the Suggested Edits queue only once, though of course subsequent edit proposals can send the same post there again. What about the other three queues?
It sounds like a question can go through the Close queue more than once if the first votes expire and then somebody votes to close again. Is that always the case? Is there a limit, or could a long-running close/reopen war send a question to the queue every time? Do the same rules apply to the Reopen queue and the Close queue?
If a post exits the Low Quality queue, do subsequent NAA or VLQ flags send it back there? I think I was told, as a moderator, that they don't and so I should handle those flags, but I can't find documentation now.
