	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.
