title: Laravel flush tag not always flushing
body: <p>I'm using redis with Laravel 4.2. Occasionally when I do this:</p>
  
  <p><code>Cache::tags('products', 'list-products')-&gt;flush()</code> </p>
  
  <p>it flushes <strong>most</strong> items but 1 or 2 may stick around. They're not being reinserted as I'm checking for that (and sometimes I'm deleting the MySQL object they're caching) and so I have to manually go into the redis server and delete those keys (which happen to match the given tags).</p>
  
  <p>Is there a way around it? Has anyone experienced this before? </p>
