Conflict in what way? If you don't have deterministic ordering on
your operations, you won't have predictable results, but the cache
will be internally consistent.
Under classic memcached, no two operations are executed at the same
time (it's single-threaded). I don't fully understand the new multi-
threaded code, but it's probably safe to assume that no two
operations touch the same cache element at the same time.
