title: Reset Redis "used_memory_peak" stat
body: <p>I'm using Redis (2.4.2) and with the INFO command I can read stats about my Redis server.</p>
  
  <p>There are many stats, including some about how much memory is used. And one is "used_memory_peak" that seems to hold the maximum amount of memory Redis has ever taken.</p>
  
  <p>I've deleted a bunch of key, and I'd like to reset this stat since it affects the scale of my Munin graphs.</p>
  
  <p>There is a CONFIG RESETSTAT command, but it doesn't seem to affect this particular stat.</p>
  
  <p>Any idea how I could do this, without having to export/delete/import my dataset ?</p>
  
  <p><strong>EDIT</strong> :</p>
  
  <p>According to @antirez himself (<a href="https://github.com/antirez/redis/issues/369#issuecomment-4289189" rel="noreferrer">issue 369 on GitHub</a>), this is an intended behavior, but it this feature could be improved to be more useful in a future release.</p>
