Do we lock the root node for the *persistent* state transfer, like in the case of the in-memory state ? Would it maybe be better to lock on the CacheLoader in question rather than on the root node ? Possible inconsistencies ? Usually, the persistent state is *much bigger* than the in-memory state, so locking the entire tree for the persistent state transfer might take a long time...
