LockRealm locks the realm making it readonly. WARNING: Realm can't be unlocked once locked. Realm can also be locked without locking realm members. Realm members can be locked when locking the realm or afterwards. This is relevant for two reasons, one so members can be modified after lock. The other is for realm owners, which can delete threads and comments after lock.
