Access to Grid members should be protected with isShardingInitialized when it can be called in both sharded and non-sharded context. This is because there is race that happens when addShard is performed, the mongod transitions from being non-sharded to sharded and calls Grid::init, which races with all other places where Grid can be accessed even in non-sharded context.
