Erik Johnston	70c52821ce	Fix race condition in room stats. (#6029 ) Broke in #5971 Basically the bug is that if get_current_state_deltas returns no new updates and we then take the max pos, its possible that we miss an update that happens in between the two calls. (e.g. get_current_state_deltas looks up to stream pos 5, then an event persists and so getting the max stream pos returns 6, meaning that next time we check for things with a stream pos bigger than 6)	2019-09-17 12:41:23 +01:00
