Expiration question

[Steven Grimm]

Memcached is an LRU cache, meaning the object that was least recently 
used will be expired to make room for a new one. "Used" in this case 
refers to either reading or writing. The behavior you want is exactly 
what it does if you don't set any expiration time at all.
