-  #   [:multithread] Wraps cache access in a Mutex for thread safety.
-  #   [:failover]    Should the client try to failover to another server if the
-  #                  first server is down?  Defaults to true.
-  #   [:timeout]     Time to use as the socket read timeout.  Defaults to 0.5 sec,
-  #                  set to nil to disable timeouts (this is a major performance penalty in Ruby 1.8).
