+# Memcached
+
+## Dependencies
+
+* libevent, http://www.monkey.org/~provos/libevent/ (libevent-dev)
+
+## Environment
+
+### Linux
+
+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).
+
+### Mac OS X
+
+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)
