    Description

      After discussion we think the memcache cache store should be removed from Moodle core and added to the plugins database.
      This does NOT effect the memcached cache store

      The biggest reason for this proposal is that unlike the memcached store the memcache store is not safe to use in situations where the memcache server is being used by other applications.
      As such this is not "multi-site safe".

      Memcached on the other hand can be made multi-site safe and is the faster of the two.
