Most users, I'm guessing, take the approach of using a development
system to track the changes to the memcached code, and only upgrading
the production systems when there's some particular change that will be
of use to them. If you're happy with memcached as it is, that seems
like it might be a better approach since it'll minimize the number of
cache resets you have to deal with.<br>

idea of memcache is not a persistent cache... everyone keeps<br>
butting heads with that concept :)<br>
<br>
if you're looking for a persistent cache that will use disks to back it
up:<br>

however, you should have in your code to hit the database/data store<br>
for the data if it's a cache miss and then update the cache - your<br>
site may be a little bit slow while it's recaching, but that's the
<br>
point. it's not a reliable data store, it's a volatile way to save<br>
trips to the database (it's just like RAM (volatile) vs. HD<br>
(non-volatile))<br>
