how to know the connection is connected. does spymemcached thread safe?

[David Luo]

I want to use spymemcached in our production.

I have some questions:

Question 1:

does spymemcached thread safe? like can I create one instance and use it in multi thread to get/set(I only need to get and set)?

Question 2:

how to know that the ClientConnection is connected or not.

I find that new MemcachedClient will never throw Exception.

this is how I do:

        try {

           mc = new MemcachedClient( new InetSocketAddress( host, port ) );

            mc.get( "test" );

            available = true;

        } catch( OperationTimeoutException e ) {

            available = false;

            mc.shutdown();

        } catch( ConnectException e ) {

            available = false;

            mc.shutdown();

        } catch( IOException e ) {

            available = false;

            mc.shutdown();

        }

do you have better way????
