Beware... this method does not actually attempt to connect to the server and port you specify! It is not a health check to tell whether memcached is actually running or not!

It merely returns the server status from the pool, which defaults to TRUE when using addServer( ) with only required arguments.

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::getExtendedStats() to force a cache-update.
