Hmm. Not sure. I'd guess we can get off the ground with set/retrieve
operations being atomic for the client, and then see if there's any
demand for doing it the other way.

Dunno about libevent, but epoll is probably an overkill here (at least 
demanding it is). Of course, we could rely on libevent and let it use
select/poll if it doesn't find epoll. Or we could eliminate the 
dependency and just do select/poll ourselves. What's could the maximum 
number of servers per request, in a large installation that uses 
memcache now? 50-60? I don't think the benefits of epoll kick in yet, 
at such small numbers.
