It's not a config option.  You just patch and it works.

And use our binary, which is built with a libevent with epoll support,
including epoll bugfixes which aren't in 0.7a (the latest libevent version
on the site).

Test it with:

$ EVENT_SHOW_METHOD=1 ./memcached

It should say "Using: epoll" or similar.
