NAME: memory_cache_mode
TYPE: memcachemode
LOC: Config
DEFAULT: always
DOC_START
        Controls which objects to keep in the memory cache (cache_mem)

        always Keep most recently fetched objects in memory (default)

        disk Only disk cache hits are kept in memory, which means
                an object must first be cached on disk and then hit
                a second time before cached in memory.

        network Only objects fetched from network is kept in memory
DOC_END

Could easily add a tunable to require more than one hit to bring a disk
object back into memory if desired.
