    If using Linux, you need a kernel with epoll.  Sure, libevent will
    work with normal select, but it sucks.

    epoll isn't in Linux 2.4, but there's a backport at:

        http://www.xmailserver.org/linux-patches/nio-improve.html

    You want the epoll-lt patch (level-triggered).

    If you're using MacOS, you'll want libevent 1.1 or higher to deal with
    a kqueue bug.

    Also, be warned that the -k (mlockall) option to memcached might be
    dangerous when using a large cache.  Just make sure the memcached machines
    don't swap.  memcached does non-blocking network I/O, but not disk.  (it
    should never go to disk, or you've lost the whole point of it)
