|Overly aggressively admitting messages may seem like the right thing to do, until you’ve wedged yourself into some unforeseen inconsistent state. You can avoid this by making each message handler atomic; see Argus. But if you can't or don't have the discipline to do that, or aren't quite sure, you must not pump. You either avoid pumping altogether or you selectively pump messages that do not touch the state encapsulated by the pump. Or you lock access to state with a non-recursive lock and run the risk of deadlock.|
