Yup that's correct. "Agents are integrated with the STM - any dispatches made in a transaction are held until it commits, and are discarded if it is retried or aborted." http://clojure.org/agents
Atoms can't do this, as they are synchronous (called and returned immediately) - hence the warning about potentially being called multiple times.
