and executed successively. Even in multithreaded mode, all commands are atomic unless the program has a bug:)The command sequence is not atomic. If you get an item with a GET command, modify it, and then want to set it back to memcached, we don't guarantee that the item is not manipulated by another process (process, not necessarily an operating system).
