What would be wrong with setting an eviction policy on the cluster so that entries are evicted older than 5 seconds? That would probably be the easiest to configure. Though, your delay approach would probably work. Just be sure to have the removal action queued and take place in a separate thread. Some sort of batched remove might work faster.
