How does the expiration feature lead to inconsistent data?  If the 
updates are hourly, then your expire time should be hourly.  To use 
memcached, you may have to rethink your system a little bit.  We have 
processes that update existing cache.  We simply overwrite it using set. 
  In fact, we never use add with memcached as we always want the new 
data to overwrite the old data.
