Reading the code, it seems like if that lock was taken, we should've seen a bunch more queries in this transaction, like some deletes, read from the archive table etc. Good point. So, other candidates are: - SqlBagOStuff::lock, which is called indirectly but a lot of different caching related things, including WANObjectCache. Which in turn is used by NameTableStore, but we should only be doing reads on that during normal operation, and not locking the database... I hope. - PageEditStash. Should only be read, not written to, while saving a new revision.
