Oro Cache Factory
Oro Cache's don't support node expiration, or even removal, but they are super fast.
Not supporting node removal allowed the authors of the Oro caches to keep nodes
in an array rather than a linked list (the way most caches do).
If your application doesn't need these features (which ShiftOne caches have) then
the Oro Cache's may be a good choice. This factory allows four different Oro
policies to be configured.
