I second the suggestion of Redis. If you need to federate the shared memory over multiple logically seperated banks of memory <i>you can use memcached</i>*. If you're on a large shared memory NUMA machine and want to do <i>true</i> shared memory via light weight threads, the scripting language [http://qore.org|Qore] may present some interesting options for you. It's very <i>perlish</i>.
