title: Memcached Client getStats list of keys for the possible stats?
body: <p>MemcachedClient has a <a href="http://dustin.github.com/java-memcached-client/apidocs/net/spy/memcached/MemcachedClient.html#getStats%28java.lang.String%29" rel="nofollow">getStats</a> method which accepts a String key for the stat value. Is there a list of possible keys I can use? </p>
  
  <p>Also is this a local operation or a blocking call to server to get those stats?</p>
