MediaWiki uses memcached, which is actually a memory caching daemon
that communicates via TCP/IP--but the daemon typically runs on
localhost.

Memcached isn't the same thing as shared memory.  You put something
into shared memory, it stays there.  You put something in memcached,
and it's only there until the daemon decides that something else it
was asked to cache is more important.
