title: memory leak in hiredis using valgrind
body: <p>I ran valgrind on my code which uses hiredis, it points out the following individual lines in my code :</p>
  
  <ul>
  <li>redisAsyncConnect()</li>
  <li>redisAsyncConnectUnix()</li>
  <li>redisLibuvAttach()</li>
  <li>uv_loop_new()</li>
  </ul>
  
  <p>I have used 'redisAsyncDisconnect' to free up the memory for the first two cases, couldn't find the right method for third one. For the fourth one i used uv_stop(). But still valgrind says there is definitely a loss in memory in all the four, what is the right way to release the memory ?</p>
