I mean improving concurrency would preferably benefit mod_cache with any cache_provider, whereas improving mod_cache_socache only (SHM, memcache, dbm, ...) wouldn't help the most used provider which is mod_cache_disk. For this reason it seems to me that concurrency improvements belongs in mod_cache itself, but without more details I can only speculate...
