ssid 706b7f8d43 Resolve race when getting approximate-memory-usage property The write operations in the table happens without holding the mutex lock, but concurrent writes are avoided using "writers_" queue. The Arena::MemoryUsage could access the blocks when write happens. So, the memory usage is cached in atomic word and can be loaded from any thread safely. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=107573379		9 年之前
