how to incrementally flush memcached nodes to avoid downtime

Question

I have a cluster of memcached nodes. Flushing the cache currently wipes all of the nodes and then a service I have running is temporarily unavailable as it re-caches.

Does anyone know how I can flush one cache, then reload it with new cache data, then flush the next node and reload it's data, and so on?

Thanks!

I created the value I want stored temporarily. When it is finished populating, I delete the old cache and swap.
