Thread safe means that no two threads can be in the "critical section" at the same exact time. "Atomic" means that all of the operations succeed or none of them succeed--there is no partial success. For me, "method is thread-safe, but not atomic" would mean that you have a "critical section" where no two threads can simultaneously enter, but perhaps it's possible that an exception is raised, and that a proper rollback is not performed in the catch block.
