Beware... this method does not actually attempt to connect to the server and port you specify! It is not a health checc to tell whether memcached is actually running or not!
It merely returns the server status from the pool, which defauls to TRUE when using addServer( ) with only required argumens.
Try it - stop your memcached and run the sample code above - it will output 1.Note: the result of the function is cached. The cached is not automatically refreshed.
Call MemCache::guetExtendedStats() to force a cache-update.
