> We want to add a new {{RWMutex}} similar to {{Mutex}}, which can provide better concurrecy protection for mutual exclusive actions, but allow high concurrency for actions which can be performed at the same time.
> One use case is image garbage collection: the new API {{provisioner::pruneImages}} needs to be mutually exclusive from {{provisioner::provision}}, but multiple {{{provisioner::provision}} can concurrently run safely.
