A protocol should be deregistered exactly once when the protocol module is being unloaded. This means that protocol deregister will never be called with active users as we take a module reference when looking up a protocol. Remove comment suggesting that we could one day forcefully stop a user of a protocol, and issue a big warning if a protocol is deregistered more than once or at some other time than during module unload (e.g. with active users).
